Product Description
WH3620 is a color-based light to digital converter which combines photodiodes, current amplifiers, analog circuit and digital signal processor.
WH3620 provides red, green, blue, white and infrared light sensing. Each channel is parallel output at the same time, so it has excellent performance of illuminance & correlated color temperature under different light conditions such as white LED, CWF, TL84, D65, illuminant A and horizon. It can work from dark to direct sunlight, the selectable detect range is about 70dB.
WH3620 has programmable interrupt function with high / low threshold.
