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

The DFRobot Gravity UV Index Sensor SEN0636 is a compact and precise sensor for detecting ultraviolet radiation in the range of 240 to 370 nm. It covers UVA, UVB, and UVC components and directly outputs the UV index (0–11), complemented by a risk level from 1 to 5. Thanks to direct output, conversion is unnecessary, greatly facilitating integration. The sensor supports both I²C and UART, making it flexible for integration into various projects. The operating voltage ranges from 3.3 V to 5 V, making it compatible with popular microcontrollers such as Arduino or ESP32. With its robust design and wide temperature range, the module is ideal for environmental monitoring, smart home systems, or use in weather and climate stations.

Features:

• The sensor measures the UV index from 0 to 11 directly and outputs a risk level.
• It covers the spectral range of 240 to 370 nm (UVA, UVB, UVC).
• The communication interfaces are I²C and UART.
• The supply voltage is 3.3–5 V.
• The standard I²C address is 0x23.
• The sensor operates reliably in the temperature range of –30 to +80 °C.
• The compact design enables easy integration into prototypes and smart home systems.

Application Examples:

• Measuring UV radiation in weather and climate stations.
• Automatic control of awnings or blinds in high UV exposure.
• UV monitoring in the garden or greenhouse for plant supervision.
• Security applications in smart homes with alerts at high UV intensity.
