Smart Home Security System Design Sensor Based on Pir and Microcontroller

Abstract

Technological developments are so rapid at this time to make people want always to be creative and trigger to create something new which can be applied and can use quickly and practically and control from close range and distance. In this research how to design home security system using PIR sensor (Passive Infra Red) based on microcontroller. Where this safety will work if the PIR (Passive Infra Red) sensor detects any human being that does not want to enter into the house, and then the micro controller process and instructs cell phone 1 to send an alarm signal in the form of SMS (Short Message Service).
