Feature:

1. Integrated Wind Speed Direction Power Sensor: One piece wind speed and direction sensor is a highly integrated product of wind speed and direction sensors, assembled with stainless steel accuracy machined parts, high strength, easier to install.
2. Accurate: One of the wind speed part of the traditional 3 wind cup structure, the wind cup selection of imported ABS materials, high strength, good start, accurate signal processing unit can be output according to user requirements of a variety of signals, large range, good linearity, easy to observe, stable and reliable.
3. Weatherproof Design: Equipped with external rain hood and internal sealing ring for IP64 level waterproof, and dustproof. The sensor exhibits good dynamic characteristics and responds well to wind direction changes. Safe to use. Boasting wonderful performance and strong stability.
4. Working Principle: Wind direction part is used to measure the horizontal wind direction of the professional meteorological instruments, its internal use of accurate angle sensors, and the use of low inertia wind vane response to the wind direction, when the wind direction changes, the tail rotates the shaft rod to drive the sensor magnet, the angle sensor senses the magnetic pole orientation changes.
5. Versatile Installation: Suitable for a variety of installation methods, special fixing accessories design, can be installed horizontally or vertically. It has a simple design, but very practical in use, giving you a good using experience.

Standard for Modbus RTU Intercom Protocol:
Serial format: 8 bit data bits, 1 stop bit, no parity bits, default baud rate is 9600bps. Set the serial debugging software to hex for sending and receiving, with at least 500ms interval between two intercom. The CRC in the manual is the parity bit, 2 bytes. The default device address is 1.
for Modbus CRC Verification Steps:
1. Preset a 16-bit register to hexadecimal FFFF, called this register the CRC Register;
2. XOR the first 8-bit data with the lower byte of the CRC register, put the result in the CRC register;
3. Shift the content of the register to the right by one bit (towards the lower bit), fill the highest bit with 0, check the lowest bit;
4. If the lowest bit is 0: repeat step 3 (shift again). If the lowest bit is 1: XOR the CRC register with the polynomial A001 (1010 0000 0000 0001);
5. Repeat steps 3 and 4 until shifting right 8 times, in this way the whole 8-bit data is processed;
6. Repeat steps 2 to 5 to process the next 8-bit data;
7. The final CRC register is the CRC code (the obtained CRC code is low before high).
Troubleshooting:
1. The fan rotates sluggish, with large latency. Due to long-term use, there may be foreign objects in the bearing or it gets stuck. Please send the sensor back to the company for processing;
2. When outputting simulated signal or RS232, RS485, the meter displays incorrect value. This may be caused by wiring problems or intercom port failure leading to the inability to get accurate data. Please check if the wiring is correct and firm, whether the serial port is occupied, and whether the serial port is set correctly;
3. If it's not for the above reasons, please contact customer service.
