The size and price of the ESP wifi modules have quickly made them into one of the preferred building blocks for IoT devices. Unfortunately they are not particularly well suited for very low power ...

Where motion sensor meets LED guide light for the ultimate fusion of hands-free convenience, energy efficiency, and ...

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 ...

PIR sensors are experiencing sustained growth in 2026 driven largely by the expansion of smart home technology and building automation.
