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
