Spec: Item Type: Wind Speed Direction Sensor Material: ABS, Aluminum Alloy Size: Approx. 458 x 232mm / 18 x 9.1in Gross Weight: Approx. 1575g/3.5lb Measuring Object: Wind Speed, Wind Direction Power Supply Voltage: DC9V-30V Signal Output: RS485 for Modbus Protocol Measuring Range: Wind Speed 0-70m/s Cable Length: Approx. 5.2m/17.1ft Accuracy: Wind Speed: ±(0.3+0.03V)m/s (V represents real time wind speed value), Wind Direction: ±3° Resolution: Wind Speed: 0.1m/s, Wind Direction: 1° Start Wind Speed: ≤0.5m/s Maximum Power Consumption: 0.9W 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-60°C Humidity: ≤100%RH Non Condensing Guard Level: IP64 Cable Rating: Rated Voltage: 300V 80°C Widely Used: Meteorology, Marine, Environmental, Airport, Port, Laboratory, Industry, , Traffic, etc. 4 Installation Methods: 1. Horizontal bottom mounting, wind direction must face upward 2. Horizontal top mounting, wind direction must face upward 3. Vertical side mounting, wind direction must face upward 4. Pole mounting, wind direction must face upward Wire Connection Method: Red Wire: Power Positive Pole Black Wire: A+ Yellow Wire: B- Green Wire: Power Negative Pole Standard for ModBus RTU Communicate Protocol: Serial Port Format: 8 data bits, 1 stop bit, no parity, default baud rate 9600bps, serial debugging software set to hex send and receive, minimum interval between two comms at least 500ms, CRC in the manual is the parity, 2 bytes. Default device address is 1. for Modbus CRC Check Steps: 1. The preset 16 bit register is hexadecimal , is called CRC register; 2. The first 8 bit data is different from the lower part of the CRC register or put the result in the CRC register; 3. Move the contents of the register to the right one bit (towards the low), fill the highest bit with 0, and check the lowest bit; 4. If the lowest position is 0: repeat step 3 (shifting again) If the lowest position is 1: the CRC register is XOR with polynomial A001 (1010 0000 0000 0001); 5. Repeat steps 3 and 4 until you move to the right 8 times, so that the entire 8 bit data has been processed; 6. Repeat Step 2 to Step 5 to process the another 8 bit data. The resulting CRC register is the CRC code (the resulting CRC code is low before high after). Troubleshooting: 1. Wind Vane/Wing rotation is not great, hysteresis is large. Due to long term use, there are foreign bodies or stuck in the bearing. 2. When analog signal or RS232, RS485 output, the instrument display value is incorrect. The correct data cannot be obtained because the cable connection is faulty or the comm serial port is faulty. Check whether the cable connection is correct and secure, whether the serial port is occupied, and whether the serial port settings are correct. How to Use: Install according to appropriate voltage DC9V-30V. PackageList: 1 x Wind Speed Direction Sensor 1 x Hex Wrench Note: 1. Please check the packaging for any damage, and verify that the product model matches the one selected. 2. Do not connect the wires while the power is on. Only turn on power after confirming proper connections. 3. The length of the sensor wire will affect the product's output signal. Do not modify the product casually during use. 4. The sensor is an accuracy device. Users should not disassemble it, expose the sensor surface to pointed objects or corrosive liquids, to avoid damaging the product.

• [Robust Weatherproof Construction] Built for outdoor use, this anemometer features an external rain cover and built-in airtight rings for ip64 and protection. the aluminum alloy body withstands harsh environments (-35°c to 60°c) while maintaining precise measurements even in 100% humidity conditions.
• [Advanced Wind Direction Detection] Equipped with precision angle sensors and a low-inertia wind vane, this meteorological instrument accurately measures horizontal wind direction. when wind direction changes, the vane rotates to drive the sensor magnet, allowing the angle sensor to detect magnetic pole orientation changes instantly with ±3° accuracy.
