The UV Radiation Testing Device operates by interfacing the GUVA-S12SD ultraviolet sensor with an Arduino board. The GUVA-S12SD sensor contains a photodiode sensitive to the UV spectrum, primarily UVA and UVB radiation, and outputs an analog voltage that scales proportionally with the measured UV light intensity. This analog signal is routed from the sensor to one of the Arduino's analog input pins. Using the Arduino IDE software, the microcontroller runs code that continuously samples this analog voltage via its internal Analog-to-Digital Converter (ADC). The board reads the raw digital value corresponding to the voltage level and applies mathematical conversions to map the reading back to a meaningful metric, such as UV Index or milliwatts per square centimeter. The entire circuit is temporarily assembled on a breadboard to manage power and signal distributions easily, utilizing standard connection wires to link the Arduino's power supply and ground rails to the sensor. A stable external power source energizes the system, enabling portable or benchtop data acquisition. While this setup captures real-time telemetry locally, advanced telemetry configurations can further transmit these logged values for remote monitoring.

Frequently Asked Questions
The sensor is primarily designed to detect UVA and UVB bands of the ultraviolet spectrum.
No, because the sensor outputs a simple analog voltage, you can read it directly using standard Arduino functions like analogRead() without installing external libraries.
The base configuration focuses on local telemetry and data logging, but you can integrate additional communication modules to achieve remote IoT logging.
