The DFRobot Gravity UV Index Sensor utilizes a high-performance UV-sensitive photodiode to detect ultraviolet radiation across the critical 240-370nm wavelength range. This covers the biologically significant UVA, UVB, and UVC bands, with a particular focus on UVB for accurate skin health risk assessment. The onboard signal conditioning and processing circuitry directly converts the raw sensor data into standardized outputs, eliminating the need for complex user-side calculations.
Designed for reliability in varied environments, the sensor operates from -30°C to 80°C and features the standard Gravity-series PH2.0 connector for easy plug-and-play connectivity. Its dual I2C and UART interfaces provide maximum compatibility with data acquisition systems, from educational Arduino setups to industrial-grade environmental monitoring stations, enabling precise tracking of UV exposure for health, agricultural, and energy applications.
