TAOS (Plano, TX) has announced the TCS3x71 and TCS3x72 Series of Digital Color RGB and Proximity Sensors. When coupled with IR LED, the sensors also provide proximity detection within a range of lighting conditions and through a variety of attenuating materials. The TCS3x72 Series is the industry’s first color sensor with an IR blocking filter integrated directly on-chip and localized only to the color sensor photodiodes. In addition, the on-chip IR blocking filter enables the devices to perform ambient light sensing (ALS).
For color sensing in closed environments with no IR light sources, the
TCS3x71 Series applications include closed-loop color temperature feedback
control in solid-state lighting (SSL) and LED RGB backlit displays.
