Color Sensor Chip - WH3620

WH3620 is a color-based light-to-digital converter that combines photodiodes, current amplifiers, analog circuits, and digital signal processors.

WH3620 provides red, green, blue, white, and infrared light sensing. Each channel outputs simultaneously in parallel, offering good illuminance and correlated color temperature performance under different lighting conditions such as white LED, CWF, TL84, D65, Illuminant A, and horizon. It can operate from darkness to direct sunlight, with a selectable detection range of approximately 70 dB.

WH3620 features programmable interrupt with high/low thresholds.
