  Christopher HuntAug 3, 2025
  If a value and are flashing alternately, it could be due to two reasons: * The sensor output is high, meaning the gas concentration exceeds the full scale. In this case, check the ambient environment. * The sensor and sensor connector are not inserted properly, or the sensor is connected backward. Ensure the sensor and connector are correctly inserted.
