+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the TAOS TSL2560/61 light-to-digital
+converters that transform light intensity into a digital signal
+output.
+These sensors contain a broadband photodiode and a infrared-responding
+photodiode allowing tye derivation of the ambient light level as
+experienced by the human eye.
+This illuminace (in lux) is made available through the
+.Xr sysctl 8
+interface.
