.. _ens210:
ams ens210 Relative Humidity and Temperature Sensor
###################################################
Overview
********
This sample application demonstrates how to use the ams ens210 sensor to
measure the ambient temperature and relative humidity.
Building and Running
********************
This sample application uses the sensor connected to the i2c stated in the
ens210.overlay file.
Flash the binary to a board of choice with a sensor connected.
For example build for a nucleo_f446re board:
.. zephyr-app-commands::
:zephyr-app: samples/sensors/ens210
:board: nucleo_f446re
:goals: build flash
:compact:
