The invention discloses a control method of a fluid flow control valve based on a sensor network; the control method is used for collecting a flow value in a pipeline in real time and comparing the flow value with a standard value; the opening degree of a valve is adjusted through a PID (Proportion Integration Differentiation) algorithm, so that the flow value and the standard value are same; and the control method specifically comprises the steps of setting the standard value, collecting flow data, collecting the opening degree of the valve, collecting time, carrying out data comparison and analysis, adjusting the opening degree of a butterfly valve, uploading data and displaying data. The control method of the fluid flow control valve based on the sensor network disclosed by the invention integrates a wireless sensor, flow detection, flow control and integral networking into a whole.
