  • 1 Gases sensors calibration process considerations

    The CO2 sensor and the O2 sensor dont need a load resistance and the measurement and calibration process is different. In the case of the CO2 sensor the sensor returns a voltage value, and this value is used to calculate the concentration, so only is necessary to configure the GAIN. The value of the GAIN in the majority of the cases is fixed at 1.
