(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 ...

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

Motion sensing technology has come a long way since its inception several years ago. Today we can find motion sensors in almost any home product, which not only adds convenience but also acts as an ...

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 ...

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 ...

Sometimes the smallest and most utilitarian thing can make the biggest difference in your home. With a proper night light, for example, there are a lot fewer accidents caused by trying to navigate in ...
