Overview
The Color 3 Click Board™ is a MikroBUS add-on board with a TCS3771 colour sensor (also known as a light-to-digital converter) and a narrow beam Infrared LED. The circuit can also function as a proximity sensor.
TCS3771 is a RGBC sensor: it can detect Red, Green, Blue and clear light. The IC performs well under a variety of lighting conditions. For example, it can be covered with different attenuation materials.
As a proximity sensor it has a large dynamic range of operation. It can take short distance measurements behind dark glass; or it can be configured for longer distance measurement, for example, human presence detection in front of monitors or laptops.
For power-saving, TCS3771 has an internal state machine that can put the device into a low power mode between successive RGBC and proximity measurements.
TCS3771 is also fast enough to give off proximity information at a high rate of repetition. This makes it useful for proximity detection in portable devices (such as a phone coming near to a speaker's ear).
The Color 3 Click Board™ communicates with the target MCU through the mikroBUS™ I2C interface, with additional functionality provided by an INT pin. Designed to use a 3.3 power supply only.
