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

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.

(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.

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 ...

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

Then you will learn how Passive Infrared motion detectors use the pyroelectric effect in commercial burglar alarms. Then you will learn how ultrasonic distance detection is accomplished, the same ...

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 ...
