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 ...

This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

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 ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a 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 Arduino-based night security light can protect your home/office from thieves/intruders at night. The light glows when movement is detected in front of the PIR sensor. Simultaneously, a piezo ...

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 this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...
