== Introduction ==

The module provides precise measurement of barometric pressure and temperature in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa absolute accuracy. As for the temperature the sensor works perfectly For temperatures between - 40 and 85 with an accuracy of ±1. Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude, we can calculate the altitude with ± 1 meter accuracy, which makes it a precise altimeter as well.
