.. _dht_polling:
Generic Digital Humidity Temperature sensor polling sample
##########################################################
Overview
********
This sample application demonstrates how to use digital humidity temperature
sensors.
Building and Running
********************
This sample supports up to 10 humidity/temperature sensors. Each sensor needs to
be aliased as ``dhtN`` where ``N`` goes from ``0`` to ``9``. For example:
.. code-block:: devicetree
/ {
aliases {
dht0 = &hs300x;
};
};
Make sure the aliases are in devicetree, then build and run with:
.. zephyr-app-commands::
:zephyr-app: samples/sensor/dht_polling
:board: <board to use>
:goals: build flash
:compact:
