Once motion is detected, the sensor sends a HIGH signal to the microcontroller, which can be used to trigger a response such as turning on an LED or activating an alarm. In this experiment, the PIR ...

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 ...

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 ...
