A method on how to realize the linearization of the sensor's nonlinearity based on wavelet is put forward in this paper for the shortcomings existing in the conventional methods such as least square regression,geometric approximation, segmental linearization and neural network etc. The algorithm, the formulae, and the self-adaptive method on deciding the numbers of wavelet radices are also presented in this paper. The nonlinear errors can be greatly reduced by employing this method. Experimental results show that this method is quite effective.
