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.

Researchers have developed a sensor that non-invasively visualises respiratory motion during X-ray and CT scans.

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 ...

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 ...

Lastly, Vooks has made an easy to understand visual guide for the patents relating to the Switch 2 Joy-Con’s computer ...

They are used in TV and AC remotes, heart rate monitoring devices, barcode scanners, motion sensors ... When it comes to currently used infrared photodiode sensors, they are typically made ...

The motion-sensor box patent reveals Nintendo's possible continued focus on motion controls, potentially accompanying the Switch 2 in some way. A recently published Nintendo patent reveals a ...
