The MQ135 air quality sensor has high sensitivity to ammonium, sulfide, benzene vapor, smoke and other harmful gases. It is capable of detecting various harmful gases, making it an economical choice suitable for multiple applications. The sensing material it uses is SnO2, which has low electrical conductivity in clean air. Therefore, when it is surrounded by polluted air, the electrical conductivity increases in proportion to the pollutants. This change in electrical conductivity can be converted to the output signal.
