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 ...

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 ...

Street crime is very common in the modern century. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. So, many security alarm systems are available ...

Introduction: In the pursuit of efficiency, automation has become a key player in simplifying daily tasks. One such innovation is the utilization of motion sensors coupled with Arduino technology to ...

Motion detection is an essential part of security systems and PIR sensor is one of the most commonly used sensor for trigging the alarms when motion is detected. This sensor can detect human/animal ...

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 ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

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 ...
