General Description

The TCS3471 family of devices provides red, green, blue, and clear light sensing (RGBC) that detects light intensity under a variety of lighting conditions and through a variety of attenuation materials. An internal state machine provides the ability to put the device into a low power mode in between RGBC measurements providing very low average power consumption. This data is transferred via an I2C to the host.

This product suits for the following applications:

  • Light color temperature measurement
  • RGB LED backlight control
  • RGB LED consistency control
  • Health fitness
  • Industrial process control
  • Medical diagnostic equipment
