Does CCS811 has any helpful value as CO2 & TVOC Sensor ...

2021-05-06· Hello, I use the CCS811 from Adafruit (NOT from China) and the example program CCS811_test from Adafruit and the Adafruit library. One change in the software: The sleep time was increased from 1000 ms to 10 000 ms. Sensor has been used for a week now, so you can assume that it is burned in. I am not expecting very accurate readings, but I thought if the increase in CO2 is …
