Does the Aranet4 compensate the CO2 reading for pressure and temperature (via gas law)? Or does one need to manually calibrate if at a higher altitude?

As stated in the Aranet4 datasheet, CO2 sensor of the device is calibrated at standard atmospheric pressure. If the device has to be used at high altitude, manual calibration of the unit should be performed. It is not intended to use the device higher than 4000 m (13 000 ft) above the sea level.
