I struggle with a BMP280, I get wrong pressure. I ordered a lot of these sensors and they give different values. I thought first it was the sensors themselves, but now I got a different program. First output from Signal K, Data browser:
environment.inside.bridge.temperature, 299.75, K, 05/23 22:07:43, OpenPlotter.I2C.BMP280
environment.outside.pressure, 111472, Pa, 05/23 22:07:43, OpenPlotter.I2C.BMP280
Then from a Python program from https://www.raspberrypi-spy.co.uk/2016/0...in-python/
pi@openplotter:~ $ python bme280.py
Chip ID : 88
Version : 0
Temperature : 24.86 C
Pressure : 1006.8111592 hPa
Humidity : 0.0 %
