4. Working Principle
The GUVA-S12SD ultraviolet sensor measures the ultraviolet intensity per unit area and outputs a corresponding voltage signal. Its workflow is as follows:
-
Power connection : Connect to the power supply via VCC and GND, supporting DC 3.3V to 5V.
-
Signal output : The sensor's output voltage changes with the intensity of ultraviolet light, outputting an analog signal.
