Principle Introduction
The sensing material of TesterMeter-MIX1035 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. TesterMeter-MIX1035 TVOC Sensor has high sensitivity to hydrogen, smoke, carbon monoxide etc. The air quality sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
