简介

The ISL29018IROZ-EVALZ evaluation board is used to evaluate the performance of Renesas' ISL29018 digital ambient light sensor and proximity sensor with interrupt function.

The ISL29018 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C interface (SMBus compatible). This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function.
