DFRobot SEN0642 RS485 UV Intensity Measurement Sensor
DFRobot SEN0642 RS485 Ultraviolet (UV) Intensity Measurement Sensor is a high‑precision device designed to measure UV intensity and UV index within the 290nm to 390nm wavelength range. Using a photoelectric detector paired with an industrial‑grade microprocessor, the DFRobot SEN0642 ensures stable and reliable performance for accurate UV monitoring. The sensor supports a wide 5VDC to 30VDC power supply and communicates via the Modbus‑RTU RS485 protocol, making it easy to integrate with Arduino and other microcontroller platforms. Built with an IP67‑rated metal aluminum shell, the sensor is durable enough for harsh outdoor environments and demanding industrial applications. Capable of detecting UV intensity from 0mW/cm2 to 15mW/cm2 and UV index values from zero to 15, the SEN0642 provides fine measurement resolution and consistent accuracy. A robust design and precise sensing capabilities make this sensor ideal for environmental monitoring, health and safety applications, agricultural UV tracking, photovoltaic system analysis, and laboratory research.
