SEN0657 Zero'ing wind issue
Richard.White 2026-04-04 08:03:27 1290 Views1 Replies I need guidance on how to properly zero wind readings. From your manual I see:
| 6001H | Wind speed zeroing register | 0x06 | Write 0xAA, wait for 10 seconds, and the device will be zeroed |
I am passing the following to the unit: 0x01, 0x06, 0x60, 0x01, 0x00, 0xAA, 0x46, 0x75.
The message appears to be acknowledged successfully (it is echo'd back two times). I delay 10 seconds after this but am still not seeing the wind zero out. What am I doing wrong??? I am testing at my desk so there is no wind!
Here's my datalog. Note how the raw wind speed reading before/after sending the command is the same:
Your command is completely correct! If the sensor reading was already accurate, it’s totally normal for the value to stay the same after zeroing. Only if the sensor shows a non-zero wind speed even in perfectly still air and zeroing doesn’t correct it, then the sensor might be faulty.
