1、Wind Speed Direction Sensor: This integrated sensor is suitable for measuring wind speed and wind direction, with a wind speed range of 0‑45m/s. Using DC5V power supply, 0‑2.5V signal output. 2、3 Cups Structure: The wind speed section adopts a 3 cups structure, and ABS material ensures high strength. It has the advantages of good startup, large range, excellent linearity, and high stability. 3、Wind Direction Part: Adopts angle sensor. When the wind direction changes, the tail wing rotates the shaft to drive the sensor magnet, and the angle sensor senses the change in magnet pole orientation. 4、Installation Methods: S type integrated wind speed and direction sensor, supporting horizontal bottom and top, vertical side and pole installation, the wind direction must face upwards, suitable for various scenarios. 5、Secure and Reliable: With high accuracy processing, the aluminum alloy shell has high strength and light weight. External rain edges cover, built in sealing ring, waterproof and dustproof, with IP64 guard level.

Standard Comm 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
CRC Check Steps:
1. The preset 16 bit register is hexadecimal FFFF, 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 (shift 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 next 8 bit data.
The resulting CRC register is the CRC code (the resulting CRC code is low before high after).
Troubleshooting:
1. Wind blade rotation is not good, 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 por
