Comments

Pressure is provided in hectopascal (hPa) and temperature in degrees Celsius (°C).

Option oversampling sets the BMP180 hardware accuracy mode which is relevant for pressure readings only.

Mode	oversampling	Internal no. of samples	Conversion time pressure max. [ms]
ultra low power	0	1	4.5
standard	1	2	7.5
high resolution	2	4	13.5
ultra high resolution	3	8	25.5

The algorithm for pressure and temperature measurement is based on the specification in the official datasheet.
