I am looking for a precise absolute barometric pressure sensor, the price and wiring system is secondary . (with breakout board , read out should be digital, and there should be a library for arduino available)
The accuracy should be better then 1 hpa in the temperature range ~ 0 - 20 °C & 300 - 1100 mbar/hpa.
As there are a lot of (a.e. I2C) sensors on the market with different datasheet specification, which don't always show the min or max error for the absolute pressure accuracy (just typically error ) this is to unsecure for me needing.
At the moment I am using the Bosch BMP180 but the min and max error is around -4 hp to + 2 hp which is to large , the a.e. Bosch BMP 280 got a better accuracy but actually I didn't find a manufacturer who is selling this sensor with a breakout board.
I would like to emphasize I am not interested in the relative pressure accuracy or on the resolution, just on the absolute pressure.
If someone got experience with other sensors which may fit, any help is welcome .
