Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...

Street crime is very common in the modern century. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. So, many security alarm systems are available ...

The outdoor lighting system glows with full brightness when movement is detected for more than a minute, thus saving energy The implementation of proper lighting systems is necessary for providing a ...

Passive Infrared (PIR) sensors are electronic devices that detect motion by sensing infrared radiation emitted by objects. Every object with a temperature above absolute zero emits infrared radiation.

Motion sensors can be built into individual luminaires or installed remotely to detect surrounding persons or objects. LED luminaires with inbuilt sensors are becoming increasingly popular and readily ...
