Description
|
|
-----------
|
|
|
|
This driver implements support for the Sensirion SHT4x chip, a humidity
|
|
and temperature sensor. Temperature is measured in degree celsius, relative
|
|
humidity is expressed as a percentage. In sysfs interface, all values are
|
|
scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
|
|
|
|
Usage Notes
|
|
-----------
|
|
|
|
The device communicates with the I2C protocol. Sensors can have the I2C
|
|
address 0x44. See Documentation/i2c/instantiating-devices.rst for methods
|
|
to instantiate the device.

|
|
|
|
=============== ============================================
|
|
temp1_input Measured temperature in millidegrees Celcius
|
|
humidity1_input Measured humidity in %H
|
|
update_interval The minimum interval for polling the sensor,
|
|
in milliseconds. Writable. Must be at least
|
|
2000.
