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.
