Introduction: GSM Based Home Security System

By

How we can protect our home and shops from thief?

In this tutorial, I will show you how to make GSM Home Security using Arduino UNO , SIM800L GSM Module and PIR Motion Sensor. This gsm based system detects motion by using pir motion sensor and sends data to Arduino and then Arduino micro controller sends call alert to the emergency number through the sim800l GSM module.

This is a very simple and easy to build home security system with just few lines of code. you can build this security system at home with a little efforts.
