GUVA-S12SD UV Sensor Module

The GUVA-S12SD UV Sensor Module is a compact ultraviolet light detection module designed to measure UV intensity in the UV-A range. It converts ultraviolet radiation into an analog voltage output that can be easily read by microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (via ADC). This module is ideal for UV index monitoring, environmental sensing, and wearable or portable UV detection projects.
