An industrial-grade RS485 UV sensor that measures ultraviolet intensity (0–15 mW/cm²) and UV index (0–15) across the 290–390 nm wavelength range, covering both UVA and UVB bands. It communicates via the Modbus-RTU protocol over RS485, making it easy to integrate with Arduino and other microcontrollers using a TTL-to-RS485 adapter.

Housed in an IP67-rated metal aluminium shell, the sensor is built for long-term outdoor and industrial use. It operates on a wide DC 5–30V power supply and delivers readings with 0.01 mW/cm² resolution and a fast 0.2-second response time.
