DEVELOPMENT OF TWO WAYS COMMUNICATION HOME ALARM SYSTEM

Abstract

Home security is essential for part for a safe home. This innovation aims in developing a low-cost and intelligent security system using passive IR, magnetic and gas and smoke sensors. Arduino board which act as a microcontroller unit receives continuous data from all these sensors and processes them. The Arduino will trigger an alarm and alert messages will be sent to user’s mobile via GSM in case of untoward situations. Sensor MQ-2 (gas and smoke sensor) is used to prevent fire damage to human life by detecting gas or smoke change beyond a certain limit. Magnetic sensor uses to detect any intrusion through doors and windows whereas the low-power Passive Infrared (PIR) detectors take advantage of pyro-electricity to detect a human body that is a constant source of infrared radiation. So, this two way home alarm system can alert user if sensor detected by calling user and user can deactivate the system via SMS. Hence the device serves the highest and effective of safety and security.
