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.

Using west:

west build -b disco_l475_iot1 samples/sensors/hts221

Using CMake and ninja:

cmake -B build -GNinja -DBOARD=disco_l475_iot1 samples/sensors/hts221
