Color 12 Click Board™

Product Code: MIKROE-5724

How Does The Color 12 Click Board™ Work? The Color 12 Click Board™ is based on the BU27006MUC-Z, an advanced digital colour sensor from Rohm Semiconductor with an integrated flicker sensing function. The primary purpose of this sensor is to sense Red, Green, Blue (RGB), and Infrared light and convert them into digital values via the I2C interface. The BU27006MUC-Z stands out with its exceptional performance, high sensitivity, wide dynamic range, and excellent IR-cut characteristics. These features allow for precise illuminance measurement, typically up to 50klx, with peak wavelengths for red, green, and blue of 645/575/460nm, respectively, providing accurate information about the intensity of ambient light. In addition, the BU27006MUC-Z excels at accurately determining the ambient light's color temperature. It can effectively detect flicker noise originating from displays and room lighting, with a typical sensitivity of 10klx. This Click board™ serves various residential and commercial lighting management applications.

It can be employed for contrast enhancement in various settings where optimal lighting conditions are necessary for an immersive visual experience. Moreover, the accurate detection of ambient light makes it suitable for applications that require precise backlight control, ensuring optimal visibility and energy efficiency. The Color 12 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. Also, it uses an interrupt pin, the INT pin of the mikroBUS™ socket, used when an interrupt occurs to alert the system when some of the results cross upper or lower threshold settings. This Click board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development. SPECIFICATIONS Type Optical Applications It can be used for residential and commercial lighting management, contrast enhancement, detection of ambient for backlight control, and more.
