Principle Introduction

The sensing material of MEWOI-MIX1008 is tin dioxide SnO2, which has low conductivity in clean air. When the hydrogen(H2) 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.

MEWOI-MIX1008 hydrogen(H2) gas has high sensitivity to hydrogen. The sensor can work in high temperature. It is low cost sensor and can be used in different applications.
