 +==== 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.

 +| high resolution | 2 | 4 | 13.5 |
 +| ultra high resolution | 3 | 8 | 25.5 |
