I’ll start my post off with wishing you the best for 2022
So, I had a question related to calibrating a digital temperature sensor!
It’s a Bosh BMP280 Digital Pressure Sensor
I have it attached to a NCD Control Everything 00I2C board for Onion,
Which has an Onion Omega2+ mounted on top
I can read it’s input for the temperature in Celsius and Fahrenheit through the provided python script of CE their GitHub (it’s a bit outdated though as there already exists python 3, but that’s not too important at the moment…)
Being totally new to python, I’m happy that I managed to read some results…
Only are these results quite off from reality.
Whilst an oldskool thermometer states that it is 19.70°C (67.46°F)
The BMP280 digital thermometer states that it is 21,17 °C (70.10°F)
So my question: Is there any way to calibrate these sensors so they give a preciser input?
