MP-135 Air Quality Detection Gas Sensor Module

The MP-135 Air Quality Detection Gas Sensor Module is a reliable and cost-effective solution for monitoring indoor air pollution and harmful gases. Built using a multilayer thick-film manufacturing process, the sensor integrates a micro alumina ceramic substrate with heaters and a metal oxide semiconductor (MOS) layer on both sides for accurate gas detection. The conductive gas sensing layer is enclosed in a protective metal shell, ensuring durability and stable performance. When harmful gases are present in the surrounding air, the sensor’s conductivity changes proportionally to the gas concentration. A simple external circuit converts this change into a measurable output signal, making it easy to interface with microcontrollers like Arduino, ESP32, and other embedded systems.
