Ambient light sensor board SR-2902 is an integrated ambient and infrared light sensor board, providing PWM , UART, and I2C interface features. The SR-2902 allows users to do dimming adjustment for display device through its PWM output signal. Its advanced self-calibrated photodiode array emulates human eye response with excellent IR rejection. The internal 16-bit ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range selection feature allows user to program the lux range for the optimized counts/lux ratio. The onboard micro controller transfers brightness data to the host control system through RS232 Interface. User can see all the light value change on host screen.
