The Gravity Analog UV Sensor V2 uses a GUVA-S12SD photodiode to detect ultraviolet radiation in the 200–370 nm (UV-A) wavelength range. It outputs a linear analogue voltage signal proportional to UV intensity, making it easy to read UV index values directly with an Arduino or other microcontroller.

Part of DFRobot's Gravity series, the sensor connects via a standard 3-pin analogue cable for plug-and-play integration. Its compact size and fast response make it suitable for both indoor and outdoor UV monitoring applications.
