GUI Settings
Setting | Default | Format | Description |
---|---|---|---|
decimals | 1 | number | How many decimals does the temperature and pressure information contain |
show-pressure | 1 | 1 or 0 | Indicates if the pressure value is displayed |
show-temperature | 1 | 1 or 0 | Indicates if the temperature value is displayed |
poll-interval | 10 | >= 1 | The poll interval in seconds |
pressure-offset | 0 | number | Correct pressure value |
temperature-offset | 0 | number | Correct temperature value |
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.
