MIX1035B TVOC Sensor--Mixsen

The sensing material of MIX1035B TVOC Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the contaminants gases 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.
