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.

The Aqara FP300 is a battery-powered presence sensor with Thread and mmWave radar, giving HomeKit precise motion and environmental detection.

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 ...

Motion detection has become an essential ingredient in traditional electronic security and now it is being utilized in access control and video surveillance systems. With more applications and so many ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...
