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 ...

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.

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

Arduino platform makers, hobbyists and developers may be interested in a new Arduino Serial Camera Module which has been created by GHI Electronics and provides the ability to capture time-lapse and ...

Anyone searching for an Arduino project to keep them busy this weekend may be interested in a new motion activated wildlife camera constructed using the Adafruit Feather M0 development board. Created ...
