This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

To detect motion using a PIR sensor connected to an Arduino and trigger an LED (using the built-in LED) when motion is sensed. Passive Infrared (PIR) sensors are electronic devices that detect motion ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

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 ...

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 ...

Abstract: In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the ...
