Development of an Arduino Based Device for Early Detection of Gas Leakage in Hospitals & Industries

Leakage of gases in a system makes infrastructures and users vulnerable, it can occur due to its environmental conditions or old groundwork. Hospitals and industries where many types of gases are used like nitrogen, mono oxide, due to small amount of concentration in air can cause toxicity whereas detection of small amount of gas at its initial stage is very difficult task. Many systems have been developed which were failed in past to give accuracy in its implementation. In this research a portable detection system for the small leakage of gases has been developed, gas sensor (MQ-2) is used to find leakage when it is at its initial phase. The sensor and transmitting module senses the change in level of gas by using a sensing circuit. When a concentration of gas reach at a specified threshold level it will activate an alarm and sends a text massage to receiving module. The proposed system works well in hospitals, home, and industries
