MQ-131 Ozone Gas Detector Sensor Module

The MQ-131 Ozone Gas Detector Sensor Module uses SnO2 as its sensitive material, which has lower conductivity in clean air. When ozone gas is present, the sensor's conductivity increases with the concentration of the gas. The sensor requires a simple electronic circuit to convert the change in conductivity into a corresponding output signal that indicates the gas concentration.

• Expose To High Temperatures: Avoid exposing the sensor to high temperatures, which may damage the sensor.,
• Use In High Humidity: Avoid using the sensor in environments with high humidity, as it may affect the sensor's performance.,
• Ignore Safety Guidelines: Do not ignore the safety guidelines and installation instructions provided with the sensor.

• Use In Ventilated Areas: Ensure the sensor is used in well-ventilated areas to accurately detect ozone levels.,
• Regular Testing: Regularly test the sensor to ensure it is functioning correctly.,
• Follow Mounting Instructions: Use the mounting holes provided to securely install the sensor.

• Minimum: 10PPB,
• Maximum: 2PPM

• Temperature: Avoid extreme temperatures,
• Humidity: Avoid high humidity levels

• Description: Connect the analog output pin to an analog input on your microcontroller. The voltage level increases with the concentration of ozone.

• Description: Connect the TTL output pin to a digital input on your microcontroller. A low signal indicates a valid ozone detection.
