Overview
Description
The ISL29020IROZ-EVALZ evaluation board is used to evaluate the performance of Renesas' ISL29020 low power, high sensitivity, light-to-digital sensor with I2C interface.
The ISL29020 is a low power, high sensitivity, integrated light sensor with I2C (SMBus compatible) interface. Its state-of-the-art photodiode array provides close to human eye response and good IR rejection. This ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range select feature allows the user to program the lux range for optimized counts/lux.
