freon gas sensor

The sensing material of MIX1021 Freon Gas Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the Freon gas exists, the conductivity of the sensor will be raise according to the gas concentration goes up. Through a simple circuit, to convert the changes of conductivity to correspond to the gas concentration.
