Installation Notes

1. When installing, please align the electrical interface with the north direction;
2. Please install the sensor horizontally. The angle between the installation base and the horizontal plane should not exceed 5° to ensure that the sensor can accurately measure the wind speed and direction at low wind speeds;
3. When installing the sensor, the wind cup should be facing upward and the base should be installed perpendicular to the installation surface.
4. The position and shape of the wind cup, windmill arm, wind direction rod and tail fin directly affect the accuracy of the sensor. During installation, please do not grasp the wind cup, windmill arm, wind direction rod and tail fin to avoid damage to the sensor;
5. The position of the counterweight has been adjusted before leaving the factory. If it needs to be readjusted, please ensure that both ends of the wind direction rod are balanced, otherwise it will affect the accuracy of the product under low wind speed.

Baud rate

| Address: 0001H The default baud rate is 9600, which is saved as 0x0096, and

other analogies (all are divided by 100 and saved in hexadecimal), for example, the baud rate is 19200, which is saved as 0x0192

Check Digit| Address: 0002H 0x0000 means no parity, 0x0001 means odd parity, 0x0002 means even parity
Wind speed value| Address: 0004H divided by 100 to get the wind speed value, the unit is m/s, for example, the read value is 0x03E8, and the actual wind speed value is 10.00m/s
Wind direction value| Address: 0005H The corresponding relationship between wind direction value and wind direction is shown in the table below

Note: Access to other addresses is prohibited.
The corresponding conversion relationship of wind direction value:

Note: The wind directions corresponding to wind direction values 1, 3, 5, 7, 9, 11, 13, and 15 are the angles between the wind directions corresponding to adjacent wind direction values. For example: the wind direction corresponding to a wind direction value of 1 is the angle between the north wind and the northeast wind, and so on for other wind direction values.
