This document describes a proposed wireless remote monitoring system that uses sensor technology and GSM mobile communication networks. The system monitors important places using sensors to detect intrusions and sends alerts to the user's mobile phone. It aims to overcome the disadvantages of existing wired monitoring systems by providing real-time alerts without depending on wired telephone networks. The proposed system has two sections - a sensor section that detects intrusions using sensors and sends alerts via GSM modem, and an intimation section that receives alerts and triggers an alarm buzzer for neighbors. It would provide fast response times and high security monitoring of homes and offices.
