MP135 MP-135 Semiconductor - type Gas Sensor Mainly For Indoor Air Quality Monitoring Detect Harmful Gases Such As CO And Alcohol
The MP135 is a planar semiconductor gas sensor designed for detecting harmful gases like hydrogen (H₂), alcohol and carbon monoxide (CO). It integrates a heater and metal oxide semiconductor material on a subminiature aluminum oxide (Al₂O₃) ceramic substrate. The electrodes lead out the electrical signals, and the entire sensing component is encapsulated in a metal socket and cap. Its working principle relies on the change of conductivity with the concentration of target gases — the higher the concentration of the detected gas, the higher the conductivity of the sensor. By means of a simple external circuit, this conductivity change can be converted into an output signal that matches the gas concentration, enabling easy integration into various detection systems.
