MIKROE Color 3 Click

Color 3 Click is a mikroBUS™ add-on board with a TCS3771 color 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). Color 3 Click 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.
