How do motion sensor lights work? Best Guideline

Security and technology run in parallel. Where there is security needed technology immediately advances with necessary measures. Motion sensor light is one of the stylish prudence of the lighting arena. These lighting are not only spruce light but it has become an important household security lighting system and curiosities not beyond that how do motion sensor lights work in various places. 

By this time these lights have proved with its feature as unique, modernistic, and exciting for property owners in commercial and residential settings like Outdoor, Garden area, indoor which include the use of a motion detector and are a set of automated lights. Also comprising robust motion sensing technology to detect movement in the target area. Importantly while the sensor is tripped the light turns on/off the system.  

The Types of Motion Sensor Lights

Nowadays, Motion sensors have become very popular considering its security and energy efficiency. It is used for burglary alarms or security cameras. In activation of these devices it senses motion covered surrounding the area of neighborhood. There are three types of motion sensors used frequently.

how do motion sensor works

Passive Infrared Motion Sensor Lights

This type of sensor lights are the most common types of motion sensors available in the marketplace. The main feature of Passive Infrared uses electronic sensors to detect body heat or infrared light radiating from the objects within its range. These types of sensors only detect movement and it can not be used to identify the exact and particular that moved around. As such passive infrared can easily be triggered by objects blown in by the wind or nocturnal animals moving within the area it can cover. 

Ultrasonic Motion Sensor Lights

These types of motion sensor lights are extraordinarily powerful, which emit ultrasonic frequencies. It works out of the range of the human ear. When the ultrasonic frequencies are ounces back from the object within its range it detects objects around its field of view. Majority uses the lights in outdoors wider coverage areas and its frequencies can be easily triggered by reflections of sounds from any corners.

Microwave Motion Sensor Lights

While consumers think to cover a wide area there is no other alternative than microwave motion sensor lights. Amazing features of these types of motion sensor lights are used electromagnetic radiation to detect motion, which is especially active in the field of view with time spent of the suspicious movement. These lights are manufactured in so highly qualitative that hardly affected by harsh outdoor environments, windy weather, rain, snow or sound vibrations from any corners. Despite this, motion sensor lights reduce the chances of false triggers.

How do Motion Sensor Lights Work?

The work of motion sensor lights is the main topic to discuss in this Article. While the new innovative products come to the marketplace, then it is important curiosities of everyone that how do motion sensor lights work surrounding areas where mounted. In what process they work are discussed below briefly.  

  1. Firstly, The work of motion sensor lights are interesting and a good learning for the consumers. The motion light sensor detects motion and triggers a particular process that is a response contingent upon a passive infrared detector (PIR or PID). Passive indicates means, the sensor does not emit or produce infrared, rather receives infrared data. In fact Passive Infrared Detector (PID) picks up on the infrared energy that is light emitted by an object, such as a person. The primary element in triggering a response acts on the difference of temperature, which is detected by the PID. 
  2. Secondly, a passive infrared detector (PID) motion sensor is typically composed of a printed circuit board with a pyroelectric sensor chip, which is hosted within a mounting structure. The structural place should be such a location where the sensor is to be completely unobstructed. The aforesaid printed circuit board serves as the decoding device and interprets the signals the pyroelectric chip receives. When the chip responds to the temperature and the amount of infrared surpasses a pre-set limit then the pyroelectric chip will release a signal, thus activating a light or an alarm.
  3. Thirdly, A small window is built into the mounted structure for infrared light to reach the chip sensor. As such directly exposing the sensor to the designated monitored area. If a person enters the given area, the change in infrared as a result of their body temperature is detected by the sensor through the small window. The window is transparent for infrared light. So it does not block any signals. But it also helps to protect the device from dust and bugs. Both of which can trigger a false response.
  4. Finally, In order to further avoid false responses, care must be taken in selecting an installation area. For avoiding contact with air vents, such as HVAC vents, it can help prevent fluctuations in air temperature from activating the sensor.

Final Recap

No confusion that home is sanctuary, and that’s why its security is paramount. While  every step of life is ensured safe, you have absolute peace of mind. Adding outdoor motion sensor lights to your home can enhance home safety and prevent burglars from breaking in. No one wants to think about the possibility that their home might be targeted for a burglary or intrusion in the middle of the night.  Installing outdoor security lights with motion sensor detection can instantly scare away a thief before they get to your front door. Therefore it is not less important to know, how do motion sensor light work and its feasibility.
