IC/Module: ISL29125 Digital RGB colour Light Sensor
ISL29125 is a low-power, high sensitivity RED, GREEN and BLUE colour light sensor that operates on an I2C interface. Its photodiode array offers an accurate RBG spectral response and excellent light source to light source variation. The ISL29125 is designed to reject IR in light sources that allows the device to operate in environments from sunlight to dark rooms.
Photodiodes and ADC
The Color 2 Click Board™ incorporates three photodiode arrays that convert light into current. After light is converted to current during the light to signal process, the current output is converted to a digital count by an on-chip Analog-to-Digital Converter (ADC). The ADC converter resolution is selectable from 12 or 16 bits. The ADC conversion time is inversely proportional to the ADC resolution.
Note: For a different sensor with similar functionality, check out the original Color Click Board™.
