MST132 Low concentration Ozone sensor O3 sensor
MST132 gas-sensitive material used in the ozone sensor is a
semiconductor metal oxide with high conductivity in clean air. When ozone is present in the sensor environment, the
conductivity of the sensor decreases with the increase of ozone
gas concentration in the air. A simple circuit is used to convert
the change in conductivity into an output signal corresponding to the concentration of
the gas.
