Description

Würth Elektronik WSEN-HIDS-2525020210002 humidity sensor

Properties

Properties not inherited from the base binding file.

Name

Type

Details

friendly-name

string

Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

precision

string

Sensor measurement precision for temperature and humidity.
Supported precision options are low, mid or high.
Defaults to mid, which is a good compromise between
current usage and precision.

Default value: mid

Legal values: 'low', 'mid', 'high'

heater

string

Activate the heater when fetching a sample for the specified amount of time.
This is only possible when the precison is set to high.
Defaults to OFF, since this option is valid for high precision
and the default precision is mid.

Default value: OFF

Legal values: 'OFF', 'ON_200MW_1S', 'ON_200MW_100MS', 'ON_110MW_1S', 'ON_110MW_100MS', 'ON_20MW_1S', 'ON_20MW_100MS'
