For temperature, relative humidity and pressure, I need reasonably precise values ...
It is an ultralowpower, highly compact and economical digital sensor module which is compatible with Arduino and CircuitPython. You can use this sensor for monitoring indoor air quality. It can be used with CircuitPython board, computer, Arduino or any other microcontroller that requires 5V DC supply for operation. Due to its extended battery life, you can use it in portable devices like ...
There is a CCS811 library which supports querying the internal firmware version of the sensor, and flashing a new firmware (latest is ). Older firmware versions used to have burnin compensation which apparently caused more harm than good (instead, new firmware requires sensors to be burnedin during 48 hours), and also relied on an external sensor for temperature compensation, which is ...

Below we have defined Pins for connection of 16*2 LCD with Arduino.
· This means when the temperature goes up and down, i’ve seen the TVOC reading go up and down as well. Hardly useful for a sensor that is supposed to tell you if your air is bad or not. Take a look at the screenshot below: You can see that both sensors react wildly to temperature. Whereas the CCS811 has a bump but not significantly.

Co2 level increases with run time and just by reset the “CO2 level” drops to 400. Assuming that, it looks like either the sensor or the libraries are not ok. And another thing, the TVOC value always follows the CO2 value. One could ...
