Sensor hangs

[pierpe83]

I have entered baseline values ​​into sgp30 according to the Adafriut forum. The indications calmed down a little. After a night spent, the sensor shows stupidity again. The eCO2 value is normal but TVOC fluctuates around 180 for no reason. Can anyone help me with this?

Can you recreate this issue by running the example sketch from the library?

[pierpe83]

I use only sketch from examples of this library. I still have the same problem that after a few hours the TVOC value increases for a reason.

I can't recreate this. I set up a Feather ESP8266 with an SGP30 breakout and ran the example sketch here:
https://github.com/adafruit/Adafruit_SGP30/blob/master/examples/sgp30test/sgp30test.ino

It's been running for about 6 hours now and still reporting generally reasonable numbers:

Raw H2 13081 	Raw Ethanol 17443
TVOC 34 ppb	eCO2 417 ppm
Raw H2 13081 	Raw Ethanol 17444
TVOC 30 ppb	eCO2 401 ppm
Raw H2 13089 	Raw Ethanol 17446
TVOC 31 ppb	eCO2 400 ppm
Raw H2 13088 	Raw Ethanol 17449
TVOC 26 ppb	eCO2 404 ppm

What kind of environment are you running in?

I am sorry for the long time without any answer but I still had to do some tests.

He works under the arduino of course with ESP8266.
I still have the same situation. The sensor when turned on shows 0 TVOC and 400 eCO2. I leave it turned on overnight and in the morning the TVOC value is freaking out. Indications are between 150 and 350 ppb.
I think well maybe the sensor is detecting something, but why after the ESP reset the TVOC value already drops to zero?

This might be hardware related. Please post about this in the forums:

and include a photo of your setup showing how everything is wired together.
