Feature:1. Highly Precise Angle Sensor: Internal use of precise angle sensor for 360 degree measurement, the wind indicator protector ensures linear and high accuracy for reliable use.2. Low Inertia ABS Construction: Utilizes low inertia ABS material for improved wind direction response, robust construction, impact resistance, and long term durability.3. Reliable Wind Direction Measurement: Operates on a rotating principle for accurate wind direction measurements, featuring no dead spots and strong lightning strike resistance.4. Versatile Applications: Widely used in gardens, greenhouses, and various fields for easy and convenient wind observation, ideal for meteorology, environmental monitoring, aerospace, and more.5. Compact and Portable Design: Small and portable design for easy installation and transportation, allowing for convenient observation of wind direction in different locations.Specification:Item Type: Wind Direction SensorMaterial: ABSWeight: Approx. 385.00g/13.58ozProduct Size: Approx. 223x190x70mm/8.78x7.48x2.76inPower Supply Voltage: DC 5VOutput: 0 to 2.5VExtension Cable Length: 0.8mAccuracy: Omni directional: ±3°Resolution: Omni directional: 1°Startup Wind Speed: ≤0.8m/sMaximum Power Consumption: 0.48WLoad Capacity: DC 12V power supply, current output impedance ≤350ΩDC24V power supply, current output impedance ≤900ΩVoltage output impedance ≥1KΩOperating Environment: Temperature -35℃ to 60℃Humidity ≤100%RH non condensingProtecting Level: IP64Cable Level: Rated voltage: 300V 80℃Application: for garden, greenhouse, environmental protecting, meteorological station, ship, dock, aquaculture, advertising barrier, weather, marine, environment, airport, port, laboratory, agriculture and traffic environment wind direction measurementInstallation Aperture: 3.2mm/0.13inMating Plug Diameter: 15mm/0.59in (recommend reserving 25mm for wiring, wire up first, then install and fix the sensor)Calculation Formula: 0 to 2.5V: F=V/2.5x359Note: F represents wind direction angle value, unit: °; V represents sensor output voltage value, VWiring Method: Red wire output signal (voltage): power positiveBlack wire output signal (voltage): power negativeYellow wire output signal (voltage): signal Troubleshooting: 1. The impeller does not rotate smoothly and is severely delayed. Due to foreign objects or jamming inside the bearing caused by long term use. Please return the sensor to the company for processing2. Analog signal, the displayed value is incorrect when RS485 output. It may be due to wiring problems or communicating port failures leading to the inability to obtain correct data. Please check if the wiring is correct and secure, whether the communicating port is in use, and whether the communicating port settings are correct.Package List:1 x Wind Direction SensorNote:1. Please check the packaging for completeness and verify that the product model matches the selection2. Do not connect the wires when the power is on. Only power on after checking the connections3. The length of the sensor wire will affect the product output signal. Do not modify the product arbitrarily during use4. The sensor is a precise device. Users should not disassemble it themselves, use cutting objects, or corrosive liquids to contact the sensor surface during use to avoid damaging the product5. Do not plug or unplug with power on6.
