Principle Introduction
The sensing material of TesterMeter-MIX1006B is tin dioxide SnO2, which has low conductivity in clean air. When the combustible/LPG 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. TesterMeter-MIX1006B Combustible(LPG) Gas Sensor has high sensitivity to LPG (propane) gas. The sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
