Hi,
I don’t know if my BME280 are faulty, one could be but all 3?
I have 3 of the Pimoroni BME280 boards, I bought them 2 years ago for a small weather station I was going to build but it was only yesterday when I got them out of their packets and soldered them to my board.
I place them with my my PiZero2 and got it running.
2 of the BME280 are reading high values on all the sensors (Temp,Pressure and Humidity)
I have check a couple of actual weather sites and a few local stations on Weather Underground to check the actual readings and mine are off.
So, it is currently outside the BME’s are reading 25deg C and 26deg C temp but according to the other live data from other weather sites it’s 15.2deg C
The BME’s are reading 1015.34hPa and 1015.19hPa but according to the other live data from other weather sites it’s 1021hPa
The BME’s are reading humidity as 31.58% and 30.31% but according to the other live data from other weather sites around 60%
Any idea it’s it possible to recalibrate them, I know I could apply an offset but I don’t know how well that offset might work say in 12 hours when it’s like midnight etc.
The BME’s are in a Stevenson box all by themselves in the northern shady side of the house, so it not near direct sunlight.The PiZero2 is in a small project box outside so it no where near the BME’s
Thanks
