Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

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 ...

This project demonstrates how to interface a PIR (Passive Infrared) motion sensor with an Arduino Uno R3 to detect movement and trigger an LED. When the PIR sensor detects motion, the LED turns on for ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

This program is useful for creating an energy-efficient lighting system that responds to motion, such as a hallway or security light, with adjustable brightness and automatic turn-off features after a ...

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.
