Different from the scheme in which a micro-electromechanical system (MEMS) pressure sensor with a specific pressure in a cavity is adopted for pressure measurement, the invention adopts a plurality of MEMS pressure sensors, namely a MEMS pressure sensor array, with different pressures in cavities located in the same chip, for the pressure measurement. When the outside pressure changes, especially when the pressure changes dramatically, the pressure in a cavity of at least one MEMS pressure sensor is enabled to be possibly close to the pressure of a measured environment, and accurate measurement of the outside pressure is then achieved by means of the good degree of linearity of a sensitive film, near an equilibrium position (the upper pressure and the lower pressure are almost the same), of the MEMS pressure sensor. Furthermore, compared with the pressure sensor with the specific pressure in the cavity, the MEMS pressure sensor array can achieve measurement in a wider pressure range. Based on the MEMS pressure sensor array, the invention further provides a manufacturing method of the MEMS pressure sensor array and a pressure measuring method used for the MEMS pressure sensor array.
