+.Sh SYNOPSIS
+.Cd "hythygtemp* at iic? addr 0x28"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides measurements from the HYT-221/271/939 humidity/temperature
+sensors via the
+.Xr envsys 4
+framework.
+The
+.Nm
+.Ar addr
+argument selects the address at the
+.Xr iic 4
+bus. The sensor chips can be reconfigured to respond to other addresses than the
+default value of 0x28.
+.Sh SEE ALSO
