{"title":"RS485 Wind Direction Transmitter","handle":"rs485-wind-direction-transmitter","url":"/products/rs485-wind-direction-transmitter","description":"The wind direction sensor is a professional meteorological instrument used to measure horizontal wind direction. It integrates a hall sensor inside. The shell and weather vane is made of aluminum alloy material and uses special mold precision die casting process, featuring small dimension tolerance and high surface accuracy. The sensor internal circuit is protected, which makes the sensor have the properties of high strength, weather resistance, anti-corrosion, and waterproof. The cable connector adopts a corrosion-resistant military plug that ensures the long service life of the product. A low-inertia wind vane is used to sense the wind direction. When the wind direction changes, the tail wing rotates to drive the axle magnet to rotate through the shaft, thereby obtaining accurate wind direction information. It can detect the 16 azimuths' natural wind directions. This high-cost performance sensor can be widely used in meteorology, ocean, environment, airports, ports, laboratories, industry, agriculture, and transportation.FeaturesHigh measurement accuracy, fast response, good interchangeabilityEasy to install and operateHigh sensitivity: start-up wind speed≤0.3m/sSuitable for various harsh environments, high wind resistance      SpecificationMeasuring Range: 16 directionsStart-up Wind Speed: 0.3m/sLead Length: 2.5m/98.43”Power Voltage: 7-24VCommunication Protocol: RS485 interface Modbus protocol    DocumentsProduct wikiShipping List  RS485 Wind Direction Transmitter                                x12.5m Wire                                                       x1  ","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2520,"title":"Default Title","sku":"DF-SEN0482","price":76.82,"on_sale":false,"in_stock":true,"available_quantity":81,"option1":"Default Title"}]}
