### Temperature sensing
The BME280 measures temperatures between -40°C and 85°C with a full accuracy range between 0°C and +65°C. The accuracy is ±0.5°c with a full resolution of 0.01°C. Since the temperature sensor in the small package is tied to the PCB board on which it is soldered placed and has some self-heating as well the temperature reading will usually be above ambient.

### Humidity sensing
Non-condensing humidity between 0% and 100% is measured with an accuracy of ±3% at a maximum resolution of 0.008%.

### Pressure sensing
The pressure sensor works in temperatures between -40°C and +85°C although the zone of full accuracy only goes from 0°C to +65°C. Pressure is measured between 300hPa and 1100hPa with an accuracy of ±1.0 hPa and a resolution of 0.2Pa

### Environment gas sensing
The gas sensor works by heating a small surface internally and measuring the resistance of the gas layer. This indicates the amount of volatile components in the air and can be used as an indicator of air quality.
