+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 Celsius
+humidity1_input Measured humidity in %H
+update_interval The minimum interval for polling the sensor,
+                in milliseconds. Writable. Must be at least
+                2000.
