With detection ranges up to 75 feet, the best outdoor motion-sensor lights come in a range of styles (from floodlights to lanterns) and can be powered in various ways.

This project demonstrates motion detection using Arduino Uno and different ESP NodeMCU modules. The system consists of two NodeMCU devices—one acting as the client and the other as the server. The ...

I find that I get a reliable detection radius at about 5 meters away, which I think is perfectly fine for most home needs and comparable to other Infrared motion sensors I’ve tested.

PIR SENSOR: A passive infrared sensor is an electronic sensor that measures infrared light radiating from objects. PIR sensors mostly used in PIR-based motion detectors. Also, it used in security ...

Detection typically ranges from 20 to 100 feet, and some motion sensor light models offer an adjustable distance feature. The angle of detection usually falls within 180 degrees horizontally.

Conventional PIR sensors—currently used for human detection in applications such as automatic lights, security lights, automated thermostats, and electronic doorbells—can only detect motion. In other ...

This work presents a system for measuring and analyzing motion, by a portable electronic device and a flexible fiber sensor. The fiber is composed of multi-walled carbon nanotubes (MWCNTs) for its ...
