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.
