LPS22HB: Temperature and Humidity Monitor
#########################################

Overview
********
This sample periodically reads pressure from the LPS22HB MEMS pressure
sensor and displays it on the console.


Requirements
************

This sample uses the LPS22HB sensor controlled using the I2C interface.

Building and Running
********************

This project outputs sensor data to the console. It requires an LPS22HB
sensor, which is present on the disco_l475_iot1 board.
