Industrial Light Sensor

(Please press icon for complete product catalog)


The SR-2902 is an integrated ambient and infrared light to digital converter board combined with a micro controller to communicate with PC through RS232 Interface. The SR-2902 is able to send PWM signal to control brightness or other applications. 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 users to program the lux range for the optimized counts/lux ratio.
