-This driver implements support for the Sensirion SHT3x-DIS and STS3x-DIS
+This driver implements support for the Sensirion SHT3x-DIS, STS3x-DIS and SHT85
 series of humidity and temperature sensors. Temperature is measured in degrees
 celsius, relative humidity is expressed as a percentage. In the sysfs interface,
 all values are scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
 
-The device communicates with the I2C protocol. Sensors can have the I2C
-addresses 0x44 or 0x45 (0x4a or 0x4b for sts3x), depending on the wiring. See
-Documentation/i2c/instantiating-devices.rst for methods to instantiate the
-device.
+The device communicates with the I2C protocol. SHT3x sensors can have the I2C
+addresses 0x44 or 0x45 (0x4a or 0x4b for sts3x), depending on the wiring. SHT85
+address is 0x44 and is fixed. See Documentation/i2c/instantiating-devices.rst for

 Even if sht3x sensor supports clock-stretch (blocking mode) and non-stretch
 (non-blocking mode) in single-shot mode, this driver only supports the latter.

          This driver can also be built as a module. If so, the module
          will be called sht3x.
