Home Security and Safety System Using Arduino Mega 2560 Controller

Abstract

Home security has been a major issue where crime is expanding and everyone needs to take legitimate measures to forestall interruption. What's more, there was a need to mechanize home with the goal that user can exploit the innovative headway such that a person going out does not get worried with the either Gas leakage or Taps leakage. The present work shows an attempt made by considering the different types of products existing and merging them to develop a new system . This system consumes comparably less power and focuses on the different security features of house .In this system various sensors have been used, Magnetic switches to check the doors and windows, The PIR sensor is used for detection of the change in the status or surroundings, IR proximity sensor mainly to Guard the chest in the Almera (Locker) where valuables are kept and also a temperature sensor to detect any changes due to use of any gas cutters by intruders. The most important sensors, Gas sensor which detects the gas leakage due to unforeseen condition, water level sensor which measures water flooded due to some faulty system or rain. The system is completely controlled by the Arduino mega controller. This responds rapidly when an intruder is detected and GSM(Global System for Mobile) module alerts the concerned authorities with the predefined message which should be embedded in microcontroller and horns the buzzer and sprays the pepper salt based on severity conditions .
