This project is an Home Alarm System made with Arduino Nano 33 IOT. The sensor used for the project is a simple PIR sensor that is activated if the correct password is typed on the keypad. If 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 ...

This ESP32 motion sensor project pairs the HC-SR501 PIR sensor with Arduino to build a real-time motion detection system with a live web dashboard. It works as a home automation trigger or as a first ...
