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 ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

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 ...
