TVOC and eCO2 Sensors • Wolles Elektronikkiste

2021-07-02· The CCS811 TVOC and eCO2 sensor calculates the output values via the resistance of a metal oxide layer, as already described. The exact correlation varies from sensor to sensor and changes over operating time. In particular, this applies to the first few days. For the calculation of the TVOC and eCO2 values, the CCS811 compares the current measured values with the so-called baseline. The ...
