1、Sturdy Construction: Made from high strength ABS material, the cups of the wind speed sensor are designed to detect even the slightest breeze. This ensures reliable and precise readings every time. 2、Lightning Interference Resistant: The wind transducer boasts a strong resistance to lightning interference, ensuring accurate readings regardless of weather conditions. Compact and lightweight. 3、Versatile Wiring Options: The wind speed sensor is adaptable to both bottom and side wiring, providing flexibility in installation and use, fitting seamlessly into a variety of setups. 4、High Pressure Resistance: The sensor is tough, capable of standing strong under varying harsh conditions including high winds. It's built to perform reliably and consistently. 5、Extendable Cable: Equipped with a 0.8 meter extendable cable, the wind sensor offers flexibility in positioning. The sealed ring design at the cable interface ensures waterproof feature. 1 x Wind Speed Sensor with Cable Item Type: Wind Speed SensorMaterial: ABSSize: Approx. 158 x 180 x 70mm / 6.2 x 7.1 x 2.8inSignal Output: 0-5VMeasurement Range: Wind speed 0-45m/sExtension Line Length: 0.8mAccuracy: ±( 0.5+ 0.02V)m/s (V represents real time wind speed value)Resolution: 0.1m/sStarting Wind Speed: ≤ 0.8m/sMaximum Power Consumption: 0.48WLoad Capacity: DC12V power supply, current output impedance ≤350ΩOperating Environment: Temperature -35℃ to 60℃, humidity ≤100%RH without condensationProtection Level: IP64Widely Used: Greenhouses, environmental protection, weather stations, ships, docks, aquaculture, advertising gate bars, meteorology, marine, environmental, airports, ports, laboratories, industrial and agricultural, and transportation environments for wind speed measurement.Weight: Approx. 272.00g / 9.59ozCalculation formula:0-5V: F=V/5 A+BF: Represents the wind speed value, m/s;A: Sensor range width (upper range minus lower range);B: The minimum range value of the sensor (lower range limit);Wiring method (wire sequence is respectively):Distribution diameter: Approx. 63mm / 2.48inInstallation diameter: Approx. 3.2mm / 0.13inTroubleshooting: 1. The wind blades do not rotate properly and have a large lag. Due to long term use, there may be foreign objects or jamming inside the bearing. Please send the sensor back to the company for processing; 2. The display value of the analog signal instrument is incorrect. Possible wiring issues or serial port failures may result in the inability to obtain correct data. Please check if the wiring is correct and secure, if the serial port is occupied, and if the serial port settings are correct;
