Häkä/kaasusensori

MQ135 gas sensor sensitive material used in the clean air, low conductivity tin oxide (SnO2). When present in the environment pollution gas sensor, conductivity sensor with the increase in air pollution in the gas concentration increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal.

MQ135 ammonia gas sensor, sulfide, benzene vapor high sensitivity, smoke and other harmful monitoring will also be ideal. The sensor can detect a variety of harmful gases, it is a low-cost sensors for a variety of applications.
