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.

Application Scenarios:

• Household and office air quality monitoring equipment, used to detect harmful gases such as CO and alcohol.
• Automatic exhaust devices, which trigger exhaust operations when harmful gas concentrations exceed the set threshold.
• Air purifiers, helping to identify air pollution levels and start purification procedures accordingly.
• Small - sized gas detection modules that require simple driving circuits and low power consumption.
