Communication Example
03 instruction
Read wind speed value:
Send: 01 03 00 00 00 01 84 0A
Response: 01 03 02 0A 02 3F 25
Data analysis: 0x0A * 256 + 0x02 = 2562, wind speed = 2562 / 100 = 25.62 m/s
06 instructions
Modify the sensor baud rate to 4800
Send: 01 06 00 C9 00 06 D9 F6
Receive: 01 06 00 C9 00 06 D9 F6
Note: After sending the modification command, you need to power off and restart the sensor before you can use the new baud rate.
