The APDS-9300 is a low-voltage digital ambient light sensor that converts light intensity to digital
signal  output  capable  of  direct  I2C  communication.  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 that represents the irradiance measured on each channel. This
digital  output  can  be  input  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  of  better  using  this  chip,  please  refer  to  its  datasheet  which  is  available  on
manufacturer’s website or under the /datasheet folder of the system CD.

Table 3-5 contains the pin names and descriptions of the ambient light sensor module.
