MIX1008 Semiconductor 100~1000ppm Hydrogen(H2) Detection Sensor
Principle Introduction:
The sensing material of 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.
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.
Feature:
High sensitivity
Low power consumption
Long life and low cost
Fast response and recovery
Application:
Domestic H2 gas leakage detectors
Portable H2 gas detectors
