The MQ2 sensor and other MQ sensors have the ability to detect various gases. The MQ2 sensor is specifically designed to detect combustible gases such as LPG (liquefied petroleum gas), butane, propane, methane, alcohol, hydrogen and smoke. These gases are commonly found in residential, industrial and automotive environments. The sensor's sensitivity and responsiveness allow it to detect even the smallest amounts of these gases, making it a valuable tool for gas leak detection, fire detection and air quality monitoring. It takes a short time to warm up in order to function correctly. The breakout board provides digital and analog information via the easyC system. Sensor values are received via easyC.
