HTS221: Temperature and Humidity Monitor
########################################

Overview
********
This sample periodically reads temperature and humidity from the HTS221
Temperature & Humidity Sensor and displays it on the console


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

This sample uses the HTS221 sensor controlled using the I2C interface.

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

 This project outputs sensor data to the console. It requires an HTS221
 sensor, which is present on the disco_l475_iot1 board.
