Sensor pairs near-invisible aesthetics with sharply higher sensitivity, targeting smarter, cleaner motion detection in buildings and lighting systems.

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.

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 ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

Movement-based lighting suggests activity inside, which helps deter opportunists. Automatic light on stairs, landings and entrances reduces falls and avoids leaving circuits on. Hands-free access ...

ICP DAS USA releases PIR-130-DC, a 1-channel passive infrared (PIR) sensor module that detects human-body generated infrared waves within a range of approximately 8 meters (315 inches) in diameter ...
