Abstract Weighing-type rain sensor It computes the value of the precipitation by weight change in rainfall.This article mainly deals with rain datas of weighing-type rain senor on July 2, 2012 in shuangliu of chengdu, use several different filtering algorithm which include wavelet filter method and exponential smoothing method to eliminate random error and system noise.Finally compared with automatic station rainfall datas, results show that wavelet algorithm is the most effective, error between it and the data of automatic station is the smallest.
