The MQ135 Gas Sensor module for air quality features sensitive SnO2 material. It has lower conductivity in clean air, but the conductivity increases with the presence and concentration of target combustible gases such as Ammonia, Sulphide, and Benze steam. The sensor is also responsive to smoke and other harmful gases, making it versatile for different applications.
