Introduction

These days, we all feel insecure of strangers invading our houses/offices/stores. The infrared Burglar Alarm system is one smart solution that could prove to be helpful in ensuring your home is safe. The infrared Burglar Alarm system is one of the important parts of home security systems. This Infrared Burglar Alarm project we will be making today is based on IR sensor that is used to detect body motion and buzzer will raise the alarm to notify us of anyone invading or trying to enter the premises thereby ensuring complete safety.

What is IR Sensor?

An infrared (IR) sensor is an electronic device that is used to detect specific characteristics like motion, heat, etc. in its surrounding by emitting/detecting IR radiations. This sensor is used to measure the heat of the target and its motion. An IR sensor comprises of two parts viz. the emitter and the receiver and this is jointly called an optocoupler or a photo-coupler. It is one of the major components we have used in making the Infrared Burglar Alarm project on the breadboard.

Building Guide

Step 1: Circuitry of the Robot

  • Powering the components
  • Powering the IR sensors
  • VCC to 5V
  • GND / to GND
  • Output to LED positive pin.
  • Buzzer pins
  • Negative to GND
  • Positive to Output of IR

Step 2: Assembly

  • Assemble all the components required

  • Connect the Buzzer with the IR’s output pin

That’s all for this Infrared Burglar Alarm project. When connected properly, this Burglar Alarm system raises the alarm to let the house/store owners about someone trying to enter the premises and steal the valuable items. Make your own Burglar Alarm system by following the procedure given above and keep your house safe of burglars.
