The wind blade does not rotate smoothly and has a large delay. There may be foreign objects or jamming in the bearings due to long term use. Please return the sensor to the company for processing;2. The instrument display value is incorrect. May be due to wiring problems or communication port failures that prevent obtaining correct data. Please check whether the wiring is correct and
