Notify me when its in stockThe sensitive compound of the MQ-131 sensor is O3 SnO2, which provides low conductivity in the presence of clean air.
In the presence of ozone, Cl2 or NO2, the conductivity of the sensor is further increased, and the increase in gas concentration is increased. The output signal based on the concentration of the detected gas allows a simplified connection with microcontrollers, PLC systems or development kits such as Raspberry and Arduino.
