A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

OPTEX, the global leader in outdoor detection innovation, is pleased to announce the QX Infinity Series (QXI), a family of high or low mount outdoor PIR and dual-technology sensors that provide a 120° ...
