Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

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 ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...
