Unleash the Power of Accurate Colour-Sensing with Color 17 Click Board™
Step into the future of colour sensing with the Color 17 Click Board™. This compact, high-performance add-on board is your ultimate solution to accurate colour-sensing. At its heart lies the OPT4048, a state-of-the-art, high-speed precision tristimulus XYZ colour sensor developed by industry leader Texas Instruments. Boasting four sensing channels, the sensor uses precision optical filters that brilliantly mimic human eye vision.
Unmatched Speed and Precision
With the Color 17 Click Board™, experience the superior blend of speed and precision. The OPT4048 sensor comes with 12 configurable conversion times, ranging from as short as 600μs to as long as 800ms. This allows for synchronous or asynchronous reading of measurements. Furthermore, the sensor is not overly sensitive to micro-shadows or small particles on the optical surface, ensuring you get reliable, precise data every time.
Endless Applications
Whether you're developing applications for camera image correction, auto-white balancing, lighting control systems, building automation and control, or even general display brightness and colour adjustments, the Color 17 Click Board™ is the perfect fit for your needs.
Backed by mikroSDK Compliant Library
To simplify your software development, the Color 17 Click Board™ is supported by a mikroSDK-compliant library packed with functions tailored to your needs.
Ready-to-Use and Fully Tested
Our commitment to quality and reliability ensures that the Color 17 Click Board™ comes to you as a fully tested product, ready to be integrated into a system equipped with a mikroBUS™ socket. Experience hassle-free, advanced colour-sensing like never before.
How Does The Color 17 Click Board™ Work?
The Color 17 Click Board™ is based on the OPT4048, a high-speed precision tristimulus XYZ colour sensor from Texas Instruments, designed to mimic the human eye's normal vision. The human eye has spectral sensitivity in short, middle, and long wavelengths but is correlated with a range of brightness. The CIE XYZ colour space represents all colour sensations visible to an average human eye, where the X is a mix of the three CIE RGB curves, the Y is the illuminance, and the Z is a quasi-equal to blue, according to the CIE 1931 model. The CIE XYZ is fixed colour space, and one must note that there is a difference between the objects that emits light (and colour) and objects that reflect light (and colour). To put it more clearly, the monitor you look at and the wall behind it.
The OPT4048 has three channels closely matching the CIE tristimulus spectra and a fourth with a wide-band spectral response. Measures from these channels give us the characteristics of the lighting environment, such as the light intensity, color, LUV coordinates, and correlated color temperature. While closely mimicking the human eye, the OPT4084 rejects the wavelengths from their peaks, especially the NIR region (infrared) the human eye does not see, which is a crucial part of this sensor.
To achieve excellent filter performance even at higher angles of light incidence, the OPT4084 uses advanced filter technology, high-resolution colour measurements, and built-in automatic full-scale light range selection logic. By default, the OPT4048 is configured to operate in an automatic full-scale range detection mode that always selects the best full-scale range setting for the given lighting conditions. There are seven full-scale range settings, one of which can also be selected manually. Setting the device to operate in automatic full-scale range detection mode frees the user from having to program their software for potential iterative cycles of measurement and readjustment of the full-scale range until good for any given measurement. It also shows excellent linearity over the entire 26-bit dynamic range of measurement from 2.15mlux up to 144klux, with a highly linear response within each range.
The Color 17 Click Board™ uses an I2C 2-Wire interface supporting a Fast mode of up to 400KHz, and I2C burst mode to communicate with the host MCU. The I2C address can be selected via the ADDR SEL jumper with 0 selected by default. The sensor has several modes of operation: Power-Down mode, Continuous mode as a normal mode of operation, and a one-shot mode in which the sensor can be triggered to work depending on the user setup. One of the triggers can be the interrupt functionality, where the INT pin is used for hardware-synchronized triggers and interrupts. The OPT4084 features a threshold detection logic that allows MCU to sleep or do other things while the sensor watches when an appropriate interrupt event occurs.
The Color 17 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.
