General description

The TCS3400 device family provides color and IR (red, green, blue, clear and IR) ambient light sensing. The improved accuracy lux and color temperature measurement from color sensing is typically used to adjust the backlight intensity and correct the display color gamut. Additionally it can be used for light source type detection as it reports the IR content of the light.

This product suits for the following applications:

  • Ambient light sensing
  • Color temperature sensing
  • Industrial process control
  • Medical diagnostics
