Principle Introduction
The sensing material of MEWOI-MIX1002B is tin dioxide SnO2, which has low conductivity in clean air. When the combustible 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. MIX1002B Combustible and Smoke Gas Sensor has high sensitivity to methane, propane butane etc. combustible gas. The sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
