TSL(4)                   BSD Kernel Interfaces Manual                   TSL(4)

NAME
     tsl -- TAOS TSL2560/61 light sensor

SYNOPSIS
     tsl* at iic?

DESCRIPTION
     The tsl 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 an infrared-responding
     photodiode allowing the ambient light level to be determined, as experi-
     enced by the human eye.  This illuminace (in lux) is made available
     through the sysctl(8) interface and can, for example, be used to adjust
     the backlight of LCD screens to lighting conditions.

SEE ALSO
     iic(4), intro(4), sensorsd(8), sysctl(8)

     The tsl driver first appeared in OpenBSD 3.9.
