AI Technical Summary
Technical Problem
Existing sensors require two separate sensors to measure temperature and pressure separately, resulting in high manufacturing costs and low accuracy that cannot meet the growing demand.
Method used
A sensor is designed, including a housing, a base and a sensing assembly that senses the temperature and pressure of the external medium through the fluid channel. The temperature sensing structure and the strained pressure sensing structure share the fluid channel, simplifying the structure.
Benefits of technology
The function of measuring temperature and pressure simultaneously is realized, which improves accuracy, simplifies structure and reduces costs.

Abstract
The utility model discloses a sensor, which comprises a shell, a base and a sensing assembly, wherein the base is provided with a first port and a second port which are opposite to each other, the first port is connected with the shell, the shell and the base jointly form a first cavity, and at least one part of the sensing assembly is located in the first cavity; the sensing assembly comprises a circuit board, a temperature sensing structure and a strain type pressure sensing structure, the temperature sensing structure and the strain type pressure sensing structure are electrically connected with the circuit board, and at least one part of the temperature sensing structure extends out of the second port of the base from the fluid channel in the first cavity so as to sense the temperature of an external medium; and the strain type pressure sensing structure is communicated with the fluid channel so as to sense the pressure of the external medium. The pressure sensor can sense the temperature and the pressure of an external medium at the same time, and is high in sensing precision and simple in structure.
