Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

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.
