The embodiment of the invention provides a data processing method and device for a sensing terminal. The data processing method of the sensing terminal comprises the following steps of: processing data of the sensing terminal; according to the information of the sensing terminals arranged in the at least two sensing areas, obtaining the information of the sensing terminals, and generating index parameters corresponding to the sensing areas, determining a nesting relationship between the at least two sensing areas based on a Pareto optimal allocation method, finally determining weights of the sensing terminals in the at least two sensing areas according to the nesting relationship between the at least two sensing areas, and finally processing data acquired by the sensing terminals based onthe weights. According to the technical scheme provided by the embodiment of the invention, the nesting relationship between the sensing areas is determined based on the Pareto optimal allocation method; and the weight corresponding to the sensing terminal in each sensing area is determined based on the nesting relationship, so that the data acquired by each sensing terminal is processed based onthe weight, the resource utilization rate of the sensing terminal is improved, the maximum application of the data is realized, and the performance of the Internet of Things control system is improved.
