Motion Sensor Remote Alarm Miami Beach Coral Gables
High power lights that illuminate all night tend to consume a lot of power which results in large electricity bills. Motion Sensor Remote Alarm Miami Beach Coral Gables. This is particularly true with remote flood lights that are bright and produce a lot of lumens. Also most solar lights aren’t able to work all night if they need to provide continuous illumination. To solve this problem a device called a motion sensor or motion detector is used together with a lighting fixture. Motion Sensor Remote Alarm Miami Beach Coral Gables.
What are motion detector and motion detection?
A motion detector or motion sensor is a device that is used for detecting a movement in a certain range in front or around the detector. Usually it is used to detect motion of humans and is used for both safety and security purposes. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Motion detection is such a process, where a special sensor is used for detecting changes of different objects (mostly humans) in the sensors detection range that can either be a remote or an indoor area. The most basic motion detectors are able to detect movement of objects in an area from 2 – 5 meters (6.5 to 16 feet) up to 20 meters (70 feet) and more.
There are different types of motion detectors from infrared, optical to radio wave and others, and each of these types are used for specific occasions. Motion Sensor Remote Alarm Miami Beach Coral Gables. For example, infrared sensors monitor changes in infrared wave or heat in the observable area and turn on a light, alarm or a security camera when changes in the infrared spectrum are detected. Detectors that use radio frequency detection sends out microwave signals to monitor a room and when an object walks in detection area the sensor detects changes in the microwave field and signals the system that there is a moving object in the room. Video cameras can also be used for motion detection by algorithmically comparing images, when someone walks into the room the picture and pixels changes and the special algorithm can detect these changes.

Where are motion sensors used?
Motion sensors are used together with some kind of other devices, such as security cameras, alarms or lightings. One of the most common usages of a motion sensor is together with an alarm system. Motion Sensor Remote Alarm Miami Beach Coral Gables. These alarm systems are installed in both individual properties as well as commercial buildings to detect motion of unwanted trespassers. When a burglar walks into the detection range of the sensor it automatically starts the alarm. Motion detectors are also used together with security cameras, when motion is detected the security camera is turned on to catch the person walking by the observed location. Motion Sensor Remote Alarm Miami Beach Coral Gables.
More advanced motion sensors are used in many new technologies, such as gaming consoles, smartphones, robotics and others. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Automatic doors with a motion sensor
Besides previously mentioned applications, motion detectors are often used together with lights and lighting systems both for security and safety purposes. Motion Sensor Remote Alarm Miami Beach Coral Gables. When a person walks into an area which is monitored by the motion sensor, the light is automatically turned on at the moment, when motion is detected. Motion activated lights are often used together with security cameras and alarms in security systems. Motion Sensor Remote Alarm Miami Beach Coral Gables.
The most popular type of motion lights is motion activated flood light. These lights are used for both safety and security purposes. Motion Sensor Remote Alarm Miami Beach Coral Gables. Motion activated remote flood lights are used for illuminating a remote area at night, starting from front door illumination to large parking lots. From safety aspect, these lights help to illuminate a dark area at night, so that a person can safely walk to the desired place, and at the same time motion detector helps to save energy by turning the light on only, when someone walks by and turning it off after the person has safely walked to the desired place. At the same time these lights can be used for security purposes to uncover a burglar from the dark and scare him away from your property. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Occupancy sensors are used in indoor places to detect if there is a movement in the room and turn the light on or off accordingly. These sensors help to save both individuals and companies a significant amount of money on electric bills each year. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Types of motion detectors
Motion detectors can be categorized into three types – active, passive and combined sensors. Each of these sensors responds to different actions and each is used in different situations. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Active sensors use a technique that sends signals or waves across the room or another place, where the sensor is installed and monitors the changes in wave response time. When an object moves in the detection area, micro or other types of transmitted waves collide with the object in the room and responds back to the detector much quicker. Motion detector is able to understand these changes and send an electrical signal to the alarm system, light or another type of device that is connected to the motion detector. Active sensors are used to detect any kind of motion in detection range, which means that wind moved tree branches could be regarded as movement and detected by the sensor, which then could trigger the remote lighting. Motion Sensor Remote Alarm Miami Beach Coral Gables.Active sensors that use microwaves for movement detection are mostly used in such applications as automatic doors on shopping malls and similar applications, but can also be found in house alarm systems and are used for indoor lighting systems. Motion Sensor Remote Alarm Miami Beach Coral Gables. Active motion sensors are not the best solution for remote lighting as the movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by the active sensor and lightning will be triggered. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Passive sensors or PIR sensors (passive infrared sensor) in opposite to active sensors does not send out anything, but sits in the corner of a wall or other place and waits for the infrared light to reach the sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables. Passive sensors scan the room or area it is installed for infrared heat that is radiated from living beings (actually heat is radiated from any object with a temperature above absolute zero, most from humans). When a human walks into the detection area of a passive sensor, it detects heat emitted from that human and triggers alarm or turns on the light. Motion Sensor Remote Alarm Miami Beach Coral Gables. These sensors would not be effective if they could get activated by a small animal or insect that moves in the detection range, however most passive sensors can be adjusted to pick up the motion of an object with a certain level of emitted heat, for example adjusting the sensor to pick up movement only by humans. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Combined (Hybrid) sensors
Another motion sensor type that has become popular recently is combined or dual technology sensors that have a combination of both active and passive sensors. It activates light or alarm only in such occasion, when motion is detected by both active and passive sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables.Combined sensors are useful for alarm systems to reduce the possibility of false alarm triggers. Motion Sensor Remote Alarm Miami Beach Coral Gables. The most popular type of dual technology sensors combines a PIR and a microwave sensor. However this technology also has its downside. It cannot provide the same level of safety as separate PIR and microwave sensors, because the alarm is triggered only when motion is detected by both sensors. So for example, if a burglar knows how to evade one of the sensors, his movement is going to be detected just by one sensor, no signal will be sent to the alarm system and it won’t be turned on. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Active, passive or combined sensors for remote and indoor lighting
When looking at motion activated flood lights you may have come across the fact that there are very few manufacturers that indicate what type of motion sensor is used for the light. However, this is because the largest part of lights (especially remote lights) has passive infrared motion sensors. Motion Sensor Remote Alarm Miami Beach Coral Gables. And if you think more, it makes a lot of sense that passive motion sensors that use heat emitted from a human are a lot better suited for lighting than active sensors that send and receives signals and detects changes in wave lengths. Active motion sensors can be found in some indoor lights and they are not the best solution for remote lighting as the movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by an active sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables.The light will get triggered much more times without a purpose, which will result in larger electricity consumption, will degrade light bulbs faster and may disturb you and your neighbors at night.
If you see that motion activated light is commercialized as „PIR sensor light” or „Light with a PIR motion sensor” you can be sure that this type of light uses a passive motion sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables.
What is a PIR detector?
A PIR is a passive infrared motion sensor. It detects infrared energy, which is in the form of a temperature that is radiated from the body of humans, animals and other objects. A PIR sensor can detect motion in certain distance and angle, so PIR sensors have different working areas. Motion Sensor Remote Alarm Miami Beach Coral Gables.
PIR sensors are simple electronic devices and their only job is to detect changes in infrared radiation in the form of heat from the detection area. Infrared light moves electrons in the sensors, which are captured and amplified into an electrical signal. This signal then is used to alert the alarm system or trigger a motion light to start illuminating. PIR sensor structure is pretty simple and consumes little energy and most basic sensors cost just a few bucks, so they are widely used in security systems for homes and businesses as well as indoor and remote lights and lighting systems, and also are used in robotics and other industries. Motion Sensor Remote Alarm Miami Beach Coral Gables.
A PIR motion detector
PIR sensors can have different adjustable settings. For example, some motion detectors can be set to respond to energy in varying temperatures. For example a PIR sensor can be set to respond only to 10-12 μm (micrometer or micron) radiation, which is the average from a human body. Motion Sensor Remote Alarm Miami Beach Coral Gables.This way the sensor will not detect motion of smaller animals like dogs and cats. Some sensors are so sensitive that they can pick up a heat emitted from birds and larger bugs and the light is turned on after motion detection.
In what application PIR detectors are used?
PIR sensors same as active sensors are mostly used in security alarm systems to detect thieves and trespassers. Motion Sensor Remote Alarm Miami Beach Coral Gables. There are even some special pet immune motion sensors that are used in indoor alarm systems and can be set to ignore animals at a specific weight. PIR sensors are often used together with active microwave sensors in security systems, to prevent false alarms triggered by one or other sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Besides alarm systems, PIR sensors are often used in motion activated lights. This includes both indoor and remote lights. Motion Sensor Remote Alarm Miami Beach Coral Gables. PIR detectors are a very popular combination with remote flood lights, as they tend to consume a lot of energy because of their brightness, and a motion sensor helps to save energy and money by turning the light on only when motion is detected in front of the light. PIR sensors are also used in solar lighting. Solar lights work on batteries that get charged in the day by sunlight and power the light at night. Based on the size of the battery lights can provide continuous illumination for a couple of minutes to few hours and larger lights can even work for all night. To prolong the illumination period solar lights are often equipped with a motion sensor. With help of a motion sensor lights that have batteries with capacity of less than an hour or even less than a half an hour can provide illumination for all night if used in an area, where the light needs to be turned on just a few times at night, for example, when used as a front door light. Motion Sensor Remote Alarm Miami Beach Coral Gables.
From what parts PIR sensor consists?
The basis of all PIR sensors is practically the same, only a few parts such as lenses are different, which is why there are PIR sensors with wider and shorter detection ranges as well as different sensitivity settings. Motion Sensor Remote Alarm Miami Beach Coral Gables.
The PIR motion detector consists of such parts:
PIR sensor – The PIR sensor is the part which is responsible for measuring the infrared light emitted from an object in its detection area. Motion Sensor Remote Alarm Miami Beach Coral Gables.The sensor is protected from outer factors such as humidity by a metal casing. On top of the casing there is a small surface with the infrared-transmitting material under which is the infrared sensor. Motion Sensor Remote Alarm Miami Beach Coral Gables. The sensor (usually there are two sensors) generates electricity from the infrared radiation or heat.
Lens – The lens is what can be seen from the outside of the detector. The lens is much wider than the sensor and its job is to bend light and focus it on the infrared sensor. The lens is made of plastic which allows light with certain wavelengths to reach the sensor under the plastic cover. Motion Sensor Remote Alarm Miami Beach Coral Gables. The large lens is made from multiple smaller Fresnel lenses, which can capture more light on a smaller lens surface than regular lenses. Lens also protects the sensor from outer objects like dust getting to the sensor. To sum up, the lens of the motion detector is responsible for a couple of tasks:
Focus the light on the infrared sensor, so it can cover much larger area;
Filter the light to capture the right wavelengths, for example to detect movement only by humans and not by smaller animals;
Protect the sensor from outer impacts and objects.
Electric circuit – This consists of some resistors, capacitors, chips and adjusters. There can be a couple of adjusters inside a motion detector light:
Sensitivity adjuster – regulates a detection range of the sensor;
Timer to set the time of how long the light needs to illuminate after motion has been detected by the sensor;
Timer to set the time of how long the light needs to be turned off after no further movement is detected. Motion Sensor Remote Alarm Miami Beach Coral Gables.
How PIR detects motion?
Infrared wavelength is longer than a wavelength of visible light, so infrared light cannot be seen by humans, but it can be captured by motion detectors. Motion Sensor Remote Alarm Miami Beach Coral Gables.Not all materials that can transmit visible light like a glass of windows are able to transmit infrared light. However materials such as silicon or different types of plastic are good for transmitting infrared waves and can also be used to filter the correct wavelengths of the infrared light.
A PIR sensor detects changes in the amount of infrared radiation in its detection area. Infrared radiation basically is heat coming from objects such as humans and the amount of infrared radiation mostly depends on the temperature of the object. Motion Sensor Remote Alarm Miami Beach Coral Gables.
PIR motion sensor operation
For example, when a human walks into the sensors detection range, the temperature in that range changes from a temperature of room objects (if used indoors), which is lower, to a temperature of a human body, which is higher and when a human walks out of the detection range the temperature changes back to the temperature of room objects. Motion Sensor Remote Alarm Miami Beach Coral Gables. A PIR sensor detects these changes in temperature and transfers them into electrical signals which are passed to the alarm system that gets activated or turns on a light that starts to illuminate.
Advantages of motion sensing lights over regular lights
Motion sensors are common options for flood lights and solar lights. Motion Sensor Remote Alarm Miami Beach Coral Gables. They offer numerous advantages for both high powered remote floodlights as well as solar lights, starting from energy savings to improving the lifetime of certain parts of lighting fixtures when compared to regular lights. Here are few advantages of motion activated lights over regular lights. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Lower energy consumption and lower electricity costs
If you have ever owned a regular flood light, you must know how much energy such a light can consume when illuminating nonstop for all night. Motion Sensor Remote Alarm Miami Beach Coral Gables. The interesting part is that in most applications we actually don’t need the light to provide continuous illumination all night long, but we need the light to be turned on in a certain situation, mostly when someone is in the area, which light should provide illumination. In these situations motion activated sensors are very useful. Motion sensor will trigger the light only when someone is moving in its detection range and will turn the light off afterward, this may be one or multiple times at night based on the area the motion light is installed. Obviously a light that illuminates for 8 full hours will consume a lot more electricity than the same light that will get triggered just a few times at night and will illuminate for a couple of hours or even less. Lower energy consumption resulted in lower electricity bills and based on the power and brightness of the fixture as well as the intensity of usage the savings on electricity may be colossal. And because most motion sensors cost just a few bucks and motion activated lights cost practically the same as regular lights, solar motion light will pay itself off in the first days to the month of usage. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Other types of lights that benefit hugely from motion sensors are solar lights. You will see much more motion activated solar lights than ones without a motion sensor, and there is a good reason for that. Motion Sensor Remote Alarm Miami Beach Coral Gables. Solar lights have built in batteries with varying capacities, solar lights with larger lead acid or lithium-ion batteries can provide continuous full night illumination, while medium and smaller light that have lower capacity Ni-MH or Ni-Cd batteries likely won’t be able to provide energy for longer than an hour or two. This is why most solar lights, especially solar flood lights, are equipped with motion sensors. Motion Sensor Remote Alarm Miami Beach Coral Gables. Solar lights are mostly used in such areas that do not require a nonstop illumination, but needs to be illuminated few times at night, such as front door lights that need to provide illumination for few minutes so you can safely walk to the house at night. Motion Sensor Remote Alarm Miami Beach Coral Gables. Also, when used for security purposes to scare unwanted trespassers off your property, whether it is a bugler or some kind of animal in your backyard. It would not make sense to use a regular flood light that would illuminate nonstop all night in these situations. These are just some basic example how solar lights benefit from a motion sensor. Same as with regular motion activated lights, the largest benefits from motion sensors for solar lights is energy conservation and ability to provide longer illumination times, while running on batteries. Motion Sensor Remote Alarm Miami Beach Coral Gables.
Longer lifetime for parts and bulbs
Because motion activated lights do not require to illuminate for such long periods of time as regular lights, they not only save more energy but also help to extend the lifespan of bulbs used in the lighting fixture. Motion Sensor Remote Alarm Miami Beach Coral Gables. This can be attributed to practically any light bulb (except CFL as continuous turning on and off will decrease the lifespan of the bulb), even LED diodes that have a much higher lifespan of 25000-50000 hours and more will benefit in the long run.
More practical to use in certain applications
Motion activated lights are simply more practical to use in some applications than regular lights, and opposite around. Motion lights will benefit in such applications that require illumination only when a person walks by a certain area or stays in that area for fixed amount of time. Motion lights will also benefit areas, where it is inconvenient or impossible to install a light switch. Motion Sensor Remote Alarm Miami Beach Coral Gables. Areas where motion lights prove to be useful are front door lights, staircase lights, garden and backyard lights, lights that provide illumination on sidewalks when walking by a personal house or commercial property, lights in basements or other places with insufficient light in a house and other similar cases.
