Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

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 ...

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 ...
