Motion detection has become an essential ingredient in traditional electronic security and now it is being utilized in access control and video surveillance systems. With more applications and so many ...

Melexis unveils the MLX90296, a new micropower linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is ...

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) ...

Melexis has unveiled the MLX90296, a new micropower linear Hall-effect sensor that draws less than 5µA at 100Hz and integrates digital filters for improved performance. Its flexible architecture is ...

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 ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

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

Why range-sensing applications are becoming more common. What’s the difference between radar and optical sensing? Why these sensors are better than using passive-infrared (PIR) technology. Anyone ...
