Abstract

The invention discloses a sensor, which comprises an upper shell, a middle shell, a lower shell, an elastic deformation disc, a resistive pressure sensor, a floater, a steel ball and a single chip microcomputer, wherein an air inlet hole is formed in the middle part of the upper shell, a middle hole is formed in the middle part of the middle shell, the upper shell is mounted on the middle shell, the middle shell is mounted on the lower shell, the elastic deformation disc is mounted at a joint of the upper shell and the middle shell, the middle part of the elastic deformation disc is positionedjust below the air inlet hole, the resistive pressure sensor is mounted at a joint of the middle shell and the lower shell, the float is placed on the upper surface of the resistive pressure sensor and passes through both ends of the middle hole, the steel ball is arranged at the upper part of the floater and is in contact with the lower surface of the elastic deformation disc in a pressed manner, and the single chip microcomputer is electrically connected with the resistive pressure sensor by means of a detection circuit. By adopting the structure, the sensor has the advantages of high detection precision and wide application range.

Description

technical field [0001] The invention relates to an electronic device, in particular to a sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. [0003] The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. [0004] The air pressure sensor is an instrument used to measure the absolute pressure of a gas. It is mainly suitable for physical experiments related to gas pressure, such ...
