Presence detection finally works in my house, and there isn't a motion sensor involved.

Aqara still makes the best mmWave presence sensors around, but the FP400 doesn’t improve much on its predecessors.

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 ...

NEW YORK--(BUSINESS WIRE)--Aqara, a leading provider of smart home products, announced the launch of its new Motion Sensor P1, an updated model of the best-selling Aqara Motion Sensor. The sensor is a ...

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

(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 ...

REVIEW – Security has always been very important to me, and ever since I purchased my home, I have been working on making sure that every side of the house including entrances has motion sensor lights ...
