P083 Gasses - SGP30 TVOC value rises incredibly high

[k-zakhariy]

After some period of time values of TVOC sensor rises to some unbelievable values - only turn off power supply helps. I also tried another power supply - same problem, could this be problem of this software, or maybe bad sensor quality ?

I would appreciate any help. Thanks in advance

Whenever the temperature rises - or the humidity changes significantly - this happens. The sensor calculates the supposed proportion without measuring it itself. In the manufacturer's library there is a possibility to include the values for temperature and humidity in the calculation - unfortunately this is missing in this implementation.

@N2k1 so it can't calculate value precisely without including temp. parameters from other devices, am i got right your point ?
