EASYBus sensor module for carbon dioxide (CO2)
HIGHLIGHTS:
excellent long-term stabilityauto-calibration procedurefor surveillance of the recommended CO2 concentration in ambient air
GENERAL:
Due to the fact that CO2 is an important indicator for the quality of air in rooms, it's super important to measure the CO2 content. The recommended CO2 limit value for ambient air is 1000 ppm. An exceeding of this limit causes tiredness and a loss of concentration. The high quality and precise CO2-module works according to the infrared principle (NDIR). An auto-calibration procedure compensates aging effects and is responsible for an excellent long term stability of this CO2-module. Additionally, there is a local display which shows beside the actual CO2 concentration, the minimum and maximum values as well as an optical alarm.
