- Purpose of use
- Calibrate BMP280 sensor, which shows 1012 at 110m on Solta island. There are nearby stations 20km away: Split (Marjan) measuring 1024.3 and Hvar island with almost the same. Reduced value was 1024.9 which may be in the precision range. Thanks.

- using the shown formula i come up with a different answer with the same inputs. using p=1012.265, h=105, t=17.19 the website calculates 1024.84. running the formula by hand and in excel i get 1004.6341. any ideas where the error is?

- We have tried it in excel, but the result was same.(1024.84)

- Purpose of use
- Calibrate BME280 sensor connected to NodeMCU ESP8266 module. Used altitude data from maps https://www.daftlogic.com/sandbox-google-maps-find-altitude.htm + temperature reading from the sensor itself and compared to the closest airport data http://tgftp.nws.noaa.gov/weather/current/SBSP.html , less than 1 Km away.
