A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

Recently, the progress of uncooled infrared (IR) sensors has been remarkable due to microelectronic systems (MEMS)-based pixel structure, in which free standing thermal isolation structures are ...

I love Aqara’s products, and if you love HomeKit, it’s a vendor you’ll want to follow. They make incredibly easy-to-use and reliable smart home products at prices that won’t empty your bank account.

Researchers at Northeastern University have developed a next generation smart sensor for the Defense Advanced Research Projects Agency (DARPA) that is capable of identifying infrared (IR) wavelengths ...

A technology that enables the fabrication of "ultra-miniature infrared sensors" in desired shapes and sizes using room-temperature three-dimensional (3D) printing has been developed for the first time ...
