Method for detecting temperature change of closed environment

Abstract

The invention discloses a method for detecting temperature change of a closed environment. A temperature sensor is manufactured in a laser direct writing manner mainly. The temperature sensor comprises two parts of a substrate and conducting material, wherein the electrical resistivity of the conducting material is changed along with the change of the closed environment so that the temperature change of the closed environment can be known. Through the utilization of the method, the temperature change of the closed environment can be detected conveniently and timely; and compared with other traditional methods, the method is low in cost and convenient to operate.

Description

technical field [0001] The invention relates to the field of environment detection and control, and more specifically, to a method for detecting temperature changes in a closed environment. Background technique [0002] Traditional environmental temperature control is achieved through a series of electronic devices such as thermistors, control circuits, and sensors. The production process of sensors involves raw material ratio, ball milling, drying, pre-burning and heat preservation, secondary ball milling, secondary drying, A series of complex processes such as coating, drying, shearing, and testing, the production process is complicated, and the requirements for the working environment are very high. Therefore, there is an urgent need for a simple and fast method to detect the ambient temperature. Contents of the invention [0003] In view of the above problems, the present invention provides a method for detecting temperature changes in a closed environment, which is ch...
