WARNING: Please do not re-calibrate your CO2 sensor without using a reference gas for proper calibration. Failure to do so may make your CO2 readings inaccurate. This option is intended to be used in a professional, industrial or research setting.
All of our Oxa CO2 sensor modules have been pre-calibrated before being sent to you, so you can start sensing right away! However, there may be an occasion where professionals would want to re-calibrate the baseline for this sensor module.
You can do this by going to your "Calibration" settings within your N+Oxa app menu, as shown here:
You will then need to use a calibration gas to calibrate your CO2 sensor module hardware for both 0 PPM as well as 400 PPM. Choose the option from the choices given to you in the "Calibration" settings respectively.
