Abstract

The invention discloses a moisture-proof sensor and a use method thereof, and belongs to the field of sensors. The moisture-proof sensor comprises a sensor body, the outer wall of the upper end of the sensor body is sleeved with a protective cover, a heat dissipation fan is fixedly installed in a heat dissipation groove, two parallel first flat plates are fixedly connected to the inner wall of the protective cover, and the two first flat plates are arranged at the lower end of the heat dissipation fan. A plurality of first through holes corresponding to each other are formed in the upper ends of the two first flat plates, a second flat plate fixedly connected with the protective cover is arranged at the lower ends of the two first flat plates, a plurality of second through holes evenly distributed are formed in the upper end of the second flat plate, and the space between the first flat plates and the second flat plate is filled with a spherical drying agent. An automatic opening and closing mechanism is arranged between the two first flat plates, and ejection mechanisms are arranged in the multiple second through holes. The sensor provided by the invention can obtain good heat dissipation performance when in use, and can obtain good moisture resistance when not in use.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a moisture-proof sensor and its usage method. 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. 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 [0003] Existing sensors will generate heat when they are used continuously. When the heat is high, the accuracy of the sensor will be affected. When the sensor is stopped, it is easily affected by moisture. damage. Contents of the invention [0004] The purpose of the pres...
