The MQ-131 Ozone Gas Detection Sensor Module is designed for detecting and measuring ozone gas (O3) concentration in the air. It utilizes a sensitive material called SnO2 (tin dioxide) to detect changes in conductivity when exposed to ozone gas. This sensor module is highly sensitive to ozone gas and can also detect other gases such as chlorine (CL2), nitrogen dioxide (NO2), and more. It converts the changes in conductivity to a corresponding output signal that represents the gas concentration. To operate the MQ-131 sensor module, a simple electronic circuit is required. This circuit allows for the proper functioning and integration of the sensor module into various applications. With its high sensitivity to ozone gas, the MQ-131 Ozone Gas Detection Sensor Module is suitable for environments where ozone monitoring is necessary, such as industrial settings, laboratories, and air quality monitoring systems. Please note that proper handling and calibration are important for accurate readings and reliable performance of the sensor module.
