Sensitive material MQ135 gas sensor is used in clean air low conductivity tin oxide (SnO2). When the sensor is kept in their environment In the polluting gases the conductivity sensor with increasing air pollution in gas concentration increases.
Using a simple circuit can change the conductivity Conversion of an output signal corresponding to the gas concentration .
MQ135 sensor for ammonia sulfide benzene vapor high sensitivity of the smoke and other harmful monitor is also very good. This sensor can be seized measure a variety of harmful gases is a lowcost sensors for a variety of applications .
