Error when opening serial monitor

[simon_swolfs]

Hi everybody,
When i upload my Arduino IDE code (look in the file attachment )everything is fine. But when i open my serial monitor, it gives this 'Exception'.

Adafruit IO connected.
Humidity: -6274.38%
Temperature is: 22.31 ºC

Exception (28):
epc1=0x402065d0 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

Code: Select all

Does anybody know what this means and what i can do to solve this problem?

Also my humidity sensor gives me very strange value: Humidity: -6274.38%

*EDIT
I did find that the problem occurs when I initiate the CCS811 code ( if (mySensor.dataAvailable())....)
If I leave that part out. Everything runs fine.

What kind of microcontroller are you using?

Hi adafruit_support_mike,
Im using a Feather Huzzah ESP8266.

A quick thing you can try is isolating the CCS811 logic and running just an example sketch.

If the example works, something is wrong in your code and you can compare the examples to see if anything is obvious.
