Status:
UV 5 Click is a compact add-on board that can measure UV radiation. This board features the AS7331, a spectral UVA/B/C sensor from ams OSRAM. The sensor can measure UVA, UVB, and UVC, which are the main types of UV rays from the UV radiation of the sunlight. It uses ADC with a high dynamic range (16… 24-bit) for measurements from low to high radiation conditions and has a high sensitivity, which makes it usable for fluorescence light conditions. This Click board™ makes the perfect solution for the development of applications for UV disinfection, UV-curving, partial discharge monitoring, analytics (water monitoring, microorganism contaminations), phototherapy, skin diagnostics, horticulture, and more.
UV 5 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

Availability date:
UV 5 Click is based on the AS7331, a spectral UVA/B/C sensor from ams OSRAM. It converts optical radiation signals to a digital result by three photodiodes of three separated UVA, UVB, and UVC channels. This way, the sensor realizes a continuous or triggered measurement. You can adjust irradiance responsivity via gain, conversion time, and internal clock frequency to affect sensitivity, full-scale range, and LSB. The gain comes in a range of 12 steps divided by a factor of two for each step, while the conversion time is internally controlled over a range of 15 steps, again by a factor of two for each step.
The AS7331 sensor operates in two different states. Configuration state enables access to the configuration settings when a measurement is impossible. Measurement state has several modes: continuous measurement mode, command measurement mode, synchronous measurement mode, and synchronous measurement start and end mode. You define the measurement mode that the sensor over the software will perform. In addition, the sensor has power-saving options, such as power down and standby.
UV 5 Click uses a standard 2-Wire I2C interface to communicate with the host MCU, supporting a bit rate of up to 400kbit/s. Select an I2C address over two ADDR SEL jumpers (0 is set by default). For externally triggered start or start and stop of the measurement, you can synchronize the SYNC input of the AS7331, which is an externally controlled conversion input. The sensor will notify the end of each conversion over the RDY pin.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
