Color sensor S9706
The S9706 is a digital color sensor that is sensitive to the red (λ=615 nm), green (λ=540 nm), and blue (λ=465 nm) regions of the spectrum. The heartbeat is serially output as 12-bit digital data. Built-in three 12-bit registers for simultaneous measurement of RGB tri-color. The sensitivity level can be adjusted in two steps to cover a wide spectral range.
Features:
  -12-bit digital output
  -Simultaneous measurement of RGB tri-color
  -Two-step sensitivity switching (sensitivity ratio of 1:9)
  -Low voltage (3.3 V) power supply
  -CMOS monolithic optical IC
  -No external components required
