This document describes a remote home security system using a wireless sensor network and GSM technology. The system aims to detect theft, gas leaks, and temperature changes and send alarm messages remotely. It uses an ARM or AT89S52 controller, GSM module, smoke sensor, LPG sensor, temperature/PIR sensor, infrared sensor, LCD, and MAX232 IC. The system's block diagram shows sensors connecting to an embedded controller that communicates via GSM to authorized mobile phones. It allows monitoring a home security system remotely.
