In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...

Security Alarm This article is about making an intruder alarm using Arduino and PIR sensor. When the PIR sensor will detect an intruder, it will send a signal to Arduino and the Arduino will sound an ...

In this project we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module.

PIR Sensor'sWorking Principle When the sensor is inactive, then the two slots sense the same amount of IR.The ambient amount radiates from the outdoors, walls or room,etc. When a human body or any ...

Whenever the animal is detected by the PIR motion sensor Arduino will be activated and buzzer will sound to get rid of animal entering the field simultaneously LED lights will flash and send message ...

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.

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!
