With higher levels of integration to include features such as occupancy detection, health monitoring, and motion and presence ...

(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.

In this modern age, IR sensors are typically used in motion detectors and the best VR headsets. In the latter, they measure the depth of a space and your proximity to things in your environment.

But you need to buy additional hardware like motion sensors to make this “magic” happen ... Performance-wise, McKinney says ...

The most common motion sensor we see in cameras is a passive infrared (PIR) sensor, which detects heat (infrared energy) that ...

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 ...

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 technology based on wireless ...
