Abstract: Security is becoming a major issue everywhere. Security is becoming necessary nowadays as the possibilities of intrusion is increasing day by day. Safety from theft, leaking of raw gas and fire are the necessary requirements for home security system. However, IoT(Internet of Things) based security systems provides enhanced security as whenever a signal from sensor occurs, a text message is sent to the desired number to take necessary actions. Here we are using an antitheft reporting system which will report the owner by ringing alarm and send a text message. Also, for the safety system in case of fire or gas leakage, it will notify the owner by sending an SMS and also by ringing an alarm.
