WSEN-HIDS: Humidity and Temperature Sensor
|
|
##########################################
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample uses the Zephyr :ref:`sensor_api` API driver to periodically
|
|
read humidity and temperature from the Würth Elektronik WSEN-HIDS
|
|
humidity & temperature sensor and displays it on the console.
|
|
|
|
By default, samples are read in polling mode. If desired, the data-ready
|
|
interrupt of the sensor can be used to trigger reading of samples.
|
|
|
|
Requirements
|
|
************
|
|
|
|
This sample requires a WSEN-HIDS sensor connected via the I2C or SPI interface.

Building and Running
|
|
********************
|
|
|
|
This sample can be configured to support WSEN-HIDS sensors connected via
|
|
either I2C or SPI. Configuration is done via the :ref:`devicetree <dt-guide>`.
|
|
The devicetree must have an enabled node with ``compatible = "we,wsen-hids";``.
|
|
See :dtcompatible:`we,wsen-hids` for the devicetree binding.
|
|
|
|
The sample reads from the sensor and outputs sensor data to the console at
|
|
regular intervals. If you want to test the sensor's trigger mode, specify
|
|
the trigger configuration in the prj.conf file and connect the interrupt
|
|
output from the sensor to your board.
