The Gravity UV Index Sensor measures ultraviolet radiation across the 240–370 nm wavelength range, covering UVA, UVB, and UVC bands. It directly outputs a UV index (0–11) and a harm risk level (1–5), eliminating the need for manual calculations.

With support for both I2C and UART communication and a 3.3–5V operating range, this sensor integrates easily with Arduino, Raspberry Pi, and other microcontroller platforms via the Gravity interface.
