A wind speed and direction sensor is a device that is used to measure the velocity and direction of the wind. It is a critical tool for many applications, including meteorology, aviation, agriculture, wind energy, and air quality monitoring, among others.Sometimes you may encounter a situation where the sensor does not work during use. Here are some common situations listed for you：
| question | possible reason | solution |
| Inaccurate measurement | The sensor is installed in the wrong position | For correct installation, follow the installation instructions |
| No change in value or no signal | Wiring errorSensor is not powered correctly | Check that the wiring is correct and secureCheck the power supply and supply it correctly |
| No communication | Basic configuration parameters such as baud rate are incorrect | Check whether the basic parameters are configured correctly according to the instructions |
| The slave address is incorrect or there are multiple devices with the same address on the bus | Verify that all addresses are unique and between 1-255 | |
| Abnormal response | Incorrect data type | Verify whether the requested register data type matches the Modbus master request. For example, you cannot use 2-byte integer data to access certain floating-point data. When requesting a certain floating-point data (2 registers/4 bytes), both registers must be requested at the same time. |
