333102 Developer boards - gas sensor, gas & smoke, MQ-2

MQ sensors, including the MQ2 sensor, are capable of detecting various gases.

The MQ2 sensor is specifically designed to detect combustible gases such as liquefied petroleum gas (LPG), 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 small 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 works with both digital (DO) and analog (AO) signals. The digital output signal is obtained by setting a threshold value with a potentiometer. The analog output signal varies depending on the intensity of the gas.
