# Title: UVC Click Board™ ## Description: How Does The UVC Click Board™ Work? The UVC Click Board™ can provide reliable and stable UVC light intensity value by using GUVC-T21GH sensor which have spectral detection range of 220nm - 280nm with output responsivity of 0.6mV/nW (at 254nm). Light intensity is converted in digital value by using MCP3221 a successive approximation A/D converter (ADC) with a 12-bit resolution. Communication to the MCP3221 is performed using a 2-wire, I2C compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are available with the device. An on-chip conversion clock enables independent timing for the I2C and conversion clocks. To get reliable readings from sensor, ADC power and voltage reference is supplied from MCP1501T-33E/RW a buffered voltage reference with 3.3V output capable of sourcing up to 20mA of current as a low-drift bandgap-based reference. The bandgap uses chopper-based amplifiers, effectively reducing the drift to zero. Second way of reading output voltage from sensor is by placing 0 ohm resistor on JP2 position labeled on PCB and reading analog value from AN pin on mikroBUS™. This way you can relay on external voltage reference and ADC with some other desired specifications for your application and you can measure light power intensity up to 14.1 mW/cm². An SMD jumper labeled as VCC SEL can be moved to the desired position, allowing both 3.3V and 5V MCUs to be used with the UVC Click Board™.

We provide a library for the UVC Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library contains basic functions for working with the UVC Click Board™.

Key Functions

Example Description

The application is composed of three sections :

void application_task ( )
{
    uint16_t raw_data;
    float voltage;
    float power;
    char demo_text[ 20 ];
    
    raw_data = uvc_read_raw_data();
    IntToStr( raw_data, demo_text );
    mikrobus_logWrite( "Raw data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    
    voltage = uvc_get_voltage();
    FloatToStr( voltage, demo_text );
    mikrobus_logWrite( "Voltage: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mV", _LOG_LINE );

    power = uvc_calculate_power( voltage );
    FloatToStr( power, demo_text );
    mikrobus_logWrite( "Power: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mW/cm2", _LOG_LINE );

    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 1500 );
}

The full application code, and ready to use projects can be found on our LibStock page.

Additional Notes and Information

Depending on the development board you are using, you may need a 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. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

MIKROSDK

The UVC Click Board™ is supported with mikroSDK - MikroElektronika 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.

The UVC Click Board™ is an ultraviolet sensing board that complements UVC Light Click Board™ for an ultimate ultraviolet solution. The board is based on a GUVC-T21GH ultraviolet sensor from GenUV, capable of measuring UVC spectrum in the range of 220nm up to 280nm and light intensity from 0mW/cm² up to 9.3mW/cm².

With high sensitivity and good solar blindness, it can be a perfect solution for monitoring sterilisation lamps used in ultraviolet germicidal irradiation (UVGI), a disinfection method that is becoming an essential tool in the battle against viruses and bacteria.

The UVC Click Board™ has two ways of reading UV sensor output, direct analogue output value and digital output thanks to the MCP3221 ADC converter.
