Versatile Wiring Options: The wind speed anemometer is compatible with both bottom and side wiring options for ease of use and adaptability. 4. Wide Application: Widely used in greenhouses, environmental protection, meteorological stations, ships, docks, aquaculture, advertising barriers, meteorology, marine, environment, airports, ports and more. 5. Premium Material: The wind cups are made from ABS material, offering high strength and requiring minimal wind speeds to engage, corrosion and erosion resistant. Specification: Item Type: Wind Speed Anemometer Material: ABS Size: Approx. 158x180x70mm/6.22x7.09x2.76in Power Supply Voltage: DC5V Signal Output: 0-2.5V Measurement Range: Wind Speed 0-45m/s Connection Extension Cable Length: Approx. 0.8m/31.50in Accuracy: ±(0.5+0.02V)m/s Resolution: 0.1m/s Start up Wind Speed: ≤0.8m/s Maximum Power Consumption: 0.48W Load Capacity: DC12V power supply, current output impedance ≤350Ω, DC24V power supply, current output impedance ≤900Ω, voltage output impedance ≥1KΩ Operating Environment: Temperature -35°C to 60°C, humidity ≤100%RH without condensation Protection Level: IP64 waterproof Application: Greenhouse, Environmental Protection, Meteorological Station, Ship, Pier, Farming, Advertising Gate, Meteorology, Marine, Environmental, Airport, Port, Laboratory, Agriculture and Traffic wind speed measurement environments Calculation Formula: 0-2.5V:F=V/2.5*A+BF: Wind speed value, m/s; V: Sensor output voltage, V; A: Sensor range width (upper range minus lower limit); B: The lowest value of the sensor range (the lower limit of the range); Wiring Method (wire color output signal): Red-Positive, Black-Negative, Yellow-Signal Diameter: Approx. 63mm/2.48in Mounting Hole Diameter: Approx. 3.2mm/0.13in Mounting Depth: Approx. 15mm/0.59in (recommend reserving 25mm for wiring, wire first, then install fixed sensor) Troubleshooting: 1. The wind blade does not rotate smoothly, the delay is large. Due to foreign objects or jamming in the bearing after long term use. Please return the sensor to the company for processing; 2. The display value is incorrect. It may be caused by wiring problems or communication interface failures that prevent correct data retrieval. Please check if the wiring is correct and secure, if the interface is occupied, and if the interface settings are correct. . Package List: 1 x Wind Speed Anemometer Note: 1.
