• Integration and calibration of non-dispersive infrared (NDIR

    Abstract. More than 300 non-dispersive infrared (NDIR) CO2 low-cost sensors labelled as LP8 were integrated into sensor units and evaluated for the purpose of long-term oper-ation in the Carbosense CO2 sensor network in Switzerland. Prior to deployment, all sensors were calibrated in a pressure and climate chamber and in ambient conditions co-located

  • Using GIS for Avalanche Hazard Mapping in Switzerland

    GIS allows the visualisation of the pressure forces on maps as well as the combination of results of varying scenarios (i.e. return periods or different release area assumptions) into a combined pressure zone map according to the Swiss Guidelines. This pressure zone map is an important base for the final delineation of the hazard map.

    the NDIR systems, respectively. The seasonality of the FTIR and the NDIR systems is 4.46 1.11 and 10.10 0.73ppm, respectively. The difference is caused by a dampening of the CO2 signal with increasing altitude due to mixing processes. Whereas the minima of both data series occur in the middle of August, the maxima of the two data sets differ by about

    Aug 01, 2016 · A pressure sensor was used to detect the pressure in the CO 2 sensor. It was reported that the detection limit of NDIR sensor was reduced from 43 ppm at atmospheric pressure to 5 ppm at 900 kPa. While the study successfully improved the detection limit, interference remained problematic.
