MH-MQ sensors are a type of gas sensor commonly used in industrial and environmental monitoring applications. These sensors are capable of detecting a wide range of gases, including volatile organic compounds (VOCs), ammonia, and hydrogen. They operate on the principle of chemoresistance, where the sensor's electrical resistance changes in response to the presence of specific gases.
