MQ2 Gas Sensor – The MQ2 is a versatile and widely used gas sensor designed to detect a variety of gases, including methane (CH4), butane (C4H10), smoke, propane (C3H8), and other harmful gases. It is commonly employed in applications like gas leak detection, smoke detection systems, and air quality monitoring. The sensor works by detecting changes in the resistance of its sensitive material in the presence of gases. It operates on a 5V power supply and can be easily interfaced with microcontrollers like Arduino to create real-time gas sensing projects for home automation, safety systems, and environmental monitoring.
