概要
説明
The ISL29038IROZ-EVALZ evaluation board is used to evaluate the performance of Renesas' ISL29038 low power ambient light and proximity sensor with enhanced infrared rejection.
The ISL29038 is a low power ambient light sensor (ALS) and proximity (PROX) sensor with a built-in IR-LED driver for proximity function. The ALS function measures the amount of light (in the visible spectrum) incident on the ISL29038. The ALS function has a programmable ambient IR-rejection, which allows fine tuning of light source variations and is ideal for light sensor applications under dark protective glass. The ALS provides a 12-bit measurement. A passive optical filter removes unwanted wavelengths (IR or ultraviolet) to ensure accurate ALS measurement.
