TSL(4) FreeBSD 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
experienced by the human eye. This illuminance (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.
