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.\n\nHoused 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.\n\nKey Features\n\n\n290–390 nm Wavelength Range – Covers UVA and UVB bands\n\nUV Intensity and Index – Measures 0–15 mW/cm² intensity and 0–15 UV index\n\nRS485 Modbus-RTU – Standard industrial communication protocol\n\nIP67 Rated – Dust-tight and water-resistant aluminium housing\n\nWide Voltage Input – DC 5–30V\n\nFast Response – 0.2-second measurement time\n\n\nSpecifications\n\n\nPower Supply – DC 5–30V\n\nWorking Current – <10 mA\n\nOutput – RS485 (Modbus-RTU)\n\nUV Intensity Range – 0–15 mW/cm²\n\nResolution – 0.01 mW/cm²\n\nAccuracy – ±10% FS (@ 365 nm, 60% RH, 25°C)\n\nUV Index Range – 0–15\n\nWavelength Range – 290–390 nm\n\nResponse Time – 0.2 s\n\nOperating Temperature – -25 to +60°C\n\nProtection Rating – IP67\n\nSensor Cable – 20 cm\n\nAdapter Cable – 70 cm\n\n\nIdeal For\n\nEnvironmental UV monitoring and climate studies\nHealth protection and UV exposure tracking\nAgricultural crop growth monitoring\nPhotovoltaic system assessment\nLaboratory UV research\n\n\nPackage Contents\n\n1× RS485 UV Sensor\n1× Adapter Cable\n1× Screw Package\n\n\nResources\n\nDFRobot Product Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":483,"title":"Default Title","sku":"DF-SEN0642","mpn":"SEN0642","price":110.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":59,"option1":"Default Title"}]}
