 Gas Leakage Sensor Gas Leakage Sensor A gas leakage sensor is an essential electronic device that detects harmful gases such as LPG, methane, or propane in the environment. It is widely used in homes, industries, and safety systems to prevent fire accidents and ensure early warning of gas leaks. How a Gas Leakage Sensor Works Most gas leakage sensors, like the MQ-series (MQ-2, MQ-5, MQ-6) , work on the principle of semiconductor gas detection . The sensor’s surface changes resistance when it comes into contact with certain gases, and this change is measured by a microcontroller (Arduino, Raspberry Pi, etc.) to trigger alarms or safety devices. Applications of Gas Leakage Sensors Home Safety Systems – Detect LPG or natural gas leaks in kitchens. Industrial Safety – Used in factories to monitor hazardous gases. Automobiles – Helps detect fuel leaks in vehicles. DIY Electronics Projects – Popular for Arduino and IoT-based safety projects. Advantages of Gas Lea...
