The study has improved the shell structure of the piezoelectric small rainfall sensor,optimized the circuit design of the rainfall measurement system,and achieved the conversion of weak charge signals to voltage signals to improve the measurement accuracy of the sensor.The experimental results show that compared with traditional tipping bucket rain gauges,the piezoelectric small rain sensor has a lower error,less than 3% .The optimized piezoelectric small rainfall sensor has significantly improved measurement accuracy and stability.It is hoped that the research results can provide reliable and effective technical support for the application of piezoelectric small rainfall sensors in meteorological monitoring and agricultural irrigation fields.
