BME280 atmospheric pressure sensor

Experimental atmospheric pressure measurement with a simple sensor: BOSCH BME280
The instrument is in the data collection box of the CR10X, the temperature and humidity do not reflect the real air conditions, because the box is in the sun and is not properly ventilated for these measurements.
