BME280 - Temperature too high

Post by doktormac »

Hi!
I am making tests with the adafruit BME280 I2C.
I have Arduino UNO Rev. 3, with the adafruit_BME280 test suite.
It works fine, exept temperature is 2.2°C too high.
What could be wrong?
I am testing a second BME280 and there the temperature is 2°C too high and the humidity 2% too low…

I am verifying with two different Humidity/Temp Devices.
Is there any possibilty to correct this with an offset?

Thanks for your help.
Thanks very much!
Peter

Post a photo showing your setup with all connections.

These are independent of the BME280? If so, what are they?

HI!
Completely different devices, one analog.

Is there any possibility to correct the offset?

You'd have to do this in your own code.

The errors you are seeing are close to spec for the sensor:
  • +/- 1 deg C
  • +/- 3% RH
