Development of Multipurpose Gas Leakage and Fire Detector with Alarm System

This project focuses on developing an electronic system that detects gas leakage and smoke giving visual level indication using LEDs. In case of high concentration gas or smoke detected, the system wirelessly activates a relay to switch off the mains thus preventing a major possibility of fire accident and also gives audio alarm for the same. The analog voltage values equivalent of smoke and gas concentration detected are wirelessly transmitted to be displayed on a computer screen periodically. The system is advantageous compared to the existing systems in the way that it is a battery powered, smart standalone module that does not require human intervention.
