Gas Leakage Detection for Avoiding Accidents

Gas leakage in our homes, industrial sectors and gas-powered vehicle etc. is a disaster waiting to happen if we don’t take the appropriate safety precautions. One of the preventive methods to stop accidents associated with gas leakage is to install a gas leakage detection device at vulnerable places. This project presents an alternative approach to develop a device that can automatically detect and control gas leakages and also monitor temperature in vulnerable areas. The system detects the leakage of the LPG (Liquefied Petroleum Gas) using a gas sensor and then also monitors the temperature using a temperature sensor. When the LPG concentration in the air exceeds a certain level, the gas sensor senses the gas leakage and the output of the sensor goes LOW, the system then opens the exit windows, and then uses a GSM module for an alert about the gas leakage. Also, when the temperature of the environment exceeds a certain limit, it then turns ON the LED (indicator) and make an alarm through the buzzer. An LCD (16×2) displays the current temperature and gas leakage status in degree Celsius and PPM respectively.
