High power lights that illuminate all night tend to consume a lot of power which results in large electricity bills. Audible Alarm Motion Sensor Miami Beach Coral Gables. This is particularly true with outdoor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

What is 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. Audible Alarm Motion Sensor 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 an outdoor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables. For example, infrared Sensors monitor changes in infrared wave or heat in the observable area and turns 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 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 special algorithm can detect these changes.

Where Motion Sensors are 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. Audible Alarm Motion Sensor 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.

More advanced Motion Sensors are used in many new technologies, such as gaming consoles, smartphones, robotics and others. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables. When a person walks by an area which is monitored by the Motion Sensor, the light is automatically turned on at the moment, when a Motion is detected. Motion activated lights are often used together with security cameras and Alarms in security systems. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables. Motion activated outdoor flood lights are used for illuminating an outdoor 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 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 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Occupancy Sensors are used in indoor places to detect if there is a movement in the room and turn light on or off accordingly. These Sensors help to save both individuals and companies significant amount of money on electric bills each year. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Types of Motion detectors

Motion detectors can be categorized in three types – active, passive and combined Sensors. Each of these Sensors respond to different actions and each are used in different situations. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Active Sensors

Active Sensors use technique that sends signals or waves across the room or other 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 other 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 outdoor lighting. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables. Active Motion Sensors are not the best solution for outdoor lighting as 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Passive Sensors

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. Audible Alarm Motion Sensor 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 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. Audible Alarm Motion Sensor 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 Motion of object with certain level of emitted heat, for example adjusting the Sensor to pick up movement only by humans. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.Combined Sensors are useful for Alarm systems to reduce possibility of false Alarm triggers. Audible Alarm Motion Sensor 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 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Active, passive or combined Sensors for outdoor and indoor lighting

When looking at Motion activated flood lights you may have come across a 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 outdoor lights) has passive infrared Motion Sensors. Audible Alarm Motion Sensor 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 sends 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 outdoor lighting as movement of random objects such as wind-blown things, smaller animals and even larger insects can be detected by an active Sensor. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

What a PIR detector is?

A PIR is a passive infrared Motion Sensor. It detects infrared energy, which is in a form of a temperature that is radiated from 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

PIR Sensors are simple electronic devices and their only job is to detect changes of infrared radiation in form of a heat from detection area. Infrared light moves electrons in the Sensors, which are captured and amplified in 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 few bucks, so they are widely used in security systems for homes and businesses as well as indoor and outdoor lights and lighting systems, and also are used in robotics and other industries. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor 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 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

Besides Alarm systems, PIR Sensors are often used in Motion activated lights. This includes both indoor and outdoor lights. Audible Alarm Motion Sensor Miami Beach Coral Gables. PIR detectors are very popular combination with outdoor flood lights, as they tend to consume lot of energy because of their brightness, and a Motion Sensor helps to save energy and money by turning the light on only when a 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 day by sunlight and power the light at night. Based on the size of the battery lights can provide continuous illumination from 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 few times at night, for example, when used as a front door light.

From what parts PIR Sensor consists?

The basis of all PIR Sensors is practically the same, only 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. Audible Alarm Motion Sensor 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. Audible Alarm Motion Sensor 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 infrared-transmitting material under which is the infrared Sensor. Audible Alarm Motion Sensor 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. Lens is much wider than the Sensor and its job is to bend light and focus it on the infrared Sensor. Lens is made from a plastic which allows light with certain wavelengths to reach the Sensor under the plastic cover. Audible Alarm Motion Sensor 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, lens of the Motion detector is responsible for 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 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. Audible Alarm Motion Sensor Miami Beach Coral Gables.

How PIR detects Motion?

Infrared wavelength is longer than a wavelength of a visible light, so infrared light cannot be seen by humans, but it can be captured by Motion detectors. Audible Alarm Motion Sensor Miami Beach Coral Gables.Not all materials that can transmit visible light like 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.
