HOW DOES IT WORK?
UVA Click as its foundation uses the GUVA-C32SM, an ultraviolet light sensor capable of measuring UV index between 0 to 14 from Genicom Co., Ltd. The GUVA-C32SM contains the GaN-based chip die, integrated amplifiers, analog-to-digital converter, digital control logic, and serial interface circuit to measure detected solar UV index in the spectral range of 220-370nm. The GUVA-C32M acquires the intensity of UVA, respectively, and outputs digital count according to each intensity. A reasonable power management mode can reduce power consumption according to specific application requirements.
UVA Click 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. Since the sensor for operation requires a 3.3V logic voltage level only, this Click board™ also features the PCA9306 voltage-level translator from Texas Instruments. The I2C interface bus lines are routed to the dual bidirectional voltage-level translator, allowing this Click board™ to work with both 3.3V and 5V MCUs properly.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development
