The invention relates to the technical field of a piezoelectric sensor, in particular to a press control module of the piezoelectric sensor. The press control module comprises a base, wherein an accommodating groove is formed in the base, a stainless steel elastic piece is arranged in the accommodating groove, a flexible printed circuit (FPC) module and an inductive chip are arranged at an upper end of the stainless steel elastic piece, a press plate is arranged at an upper end of the base, a press part is arranged at an upper end of the press plate, a prop-against convex block is arranged ata lower end of the press plate and props against the stainless steel elastic piece, and a signal connection terminal is arranged at a lower end of the base and is electrically connected with the FPC module. By pressing the press plate, the stainless steel elastic piece is pressed and deformed, the inductive chip is used for sensing deformation of the stainless steel elastic piece, converting the information to a signal an
