This project aims to develop a low-power home security alarm system using wireless sensor networks and GSM technology. It can detect theft, gas leaks, fires and send alarm messages remotely. The system uses sensors like smoke, LPG, temperature, infrared connected to a microcontroller that communicates with a GSM module. When thresholds are exceeded, the GSM module sends SMS alerts to authorized users. The technology allows for easy installation but remote security with potential drawbacks in cost and reliability.
