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 ...

PIR（Passive Infrared Detection）are used to detect motion of human movement. This version has a large lens which can support long range and wide angle. 2.54mm ...

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

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 ...

The system is designed with edge detection logic, ensuring the alert is triggered only once per motion event, similar to real-world security systems.
