Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

The ability to detect human presence can be a pretty powerful attribute for a number of devices. Versions of this technology have been around for quite some time, but artificial intelligence and ...

In this video, I'm looking at the LD2410 mmWave human body proximity sensor. The sensor operates at 24GHz and is typically used to detect human presence. Opposing to how usual PIR sensors work, the ...

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) ...
