Gravity: UV Index Sensor (240-370nm, UVA, UVB, UVC)

The Gravity UV Index Sensor is a high-sensitivity device designed to measure ultraviolet (UV) radiation within the 240-370nm range, covering UVA, UVB, and UVC wavelengths. Optimized for UVB detection, it is ideal for applications such as skin health assessment and UV index monitoring. The sensor provides a direct UV index output from 0 to 11 and a harm risk warning from 1 to 5, eliminating the need for additional calculations. It supports both I2C and UART communication, ensuring compatibility with various master control systems.

Key Features

Direct UV Index and Harm Level Output

This sensor delivers real-time UV index values (0-11) and harm levels (1-5) without requiring data conversion. This simplifies usage, making it well-suited for real-time UV monitoring and skin damage risk assessment.

Wide UV Wavelength Detection

Capable of measuring UV radiation across 240-370nm, the sensor effectively detects UVA, UVB, and UVC rays. Its focus on UVB makes it particularly useful for skin health monitoring and environmental UV assessments.

Dual Communication Modes (I2C & UART)

With support for both I2C and UART protocols, the sensor integrates seamlessly with a wide range of systems, making it ideal for applications such as environmental monitoring and photovoltaic system optimization.

Understanding Ultraviolet (UV) Wavelengths

Ultraviolet radiation consists of electromagnetic waves shorter than visible light, typically ranging from 10nm to 400nm. Measuring UV radiation is crucial for assessing health risks, such as skin and eye damage, as well as for applications in environmental monitoring and UV-based sterilization systems.
