The APDS-9300 is a low-voltage digital ambient light sensor that convert light intensity to digital
signal output and communicate in I2C protocol. Each device consists of one broadband photodiode
(visible plus infrared) and one infrared photodiode. Two integrating ADCs convert the
photodiode
currents to a digital output, which represents the irradiance measured from each channel. This
digital output is entered to a microprocessor where luminance (ambient light level) in lux is derived
using an empirical formula to approximate the human-eye response. For more detailed information
about this chip, please refer to its datasheet, which is available on manufacturer’s website or under
the
datasheet
folder of the system CD.
