Standard infrared motion detectors aren't always the best tools for the job. There are some compelling reasons to choose ...

Between infrared detection and microwave sensing, motion sensors can accurately identify movement within their field of view. They analyze changes in energy levels, whether through heat signatures ...

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 sensors are used for ...

Jennifer Pattison Touhy has a story on The Verge today about a technology debuting soon that turns existing smart lights into motion sensors: Sensify is a proprietary ... “equivalent or superior” to ...

As an example, [Circuit Valley] has an IKEA Vallhorn motion sensor for a teardown, it’s as you might expect, a passive infrared sensor (PIR) sensor coupled with a Zigbee interface. Inside the ...
