## Description

The Gravity: UV Index Sensor is a highly sensitive device designed to measure ultraviolet (UV) radiation in the wavelength range of **240-370 nm, which includes UVA, UVB, and UVC wavelengths.** The sensor primarily focuses on the UVB range, making it ideal for applications such as skin health assessment and UV index monitoring. This device directly outputs the UV index from 0 to 11 and provides a harm risk warning from 1 to 5, eliminating the need for additional calculations. It is versatile, supporting both I2C and UART communication methods, ensuring compatibility with a wide range of master control systems.

**Direct UV Index and Harm Level Output**

The UV Index 240-370 Sensor provides real-time UV index values ranging from 0 to 11 and harm levels from 1 to 5, offering immediate data without the need for conversion. This direct output simplifies the process for users, making it particularly useful for real-time monitoring of UV radiation and assessing the risk of skin damage.

**Wide UV Wavelength Range**The sensor measures UV radiation across the 240-370 nm range, covering the UVA, UVB, and UVC segments. With a focus on the UVB range, it can be effectively used for applications like skin health monitoring and environmental UV radiation assessments.

**Dual Communication Modes (I2C & UART)**

With support for both I2C and UART communication protocols, the sensor can be easily integrated with a variety of systems and devices. This flexibility makes it suitable for diverse applications, from environmental monitoring to photovoltaic system optimization.
