Abstract

The invention provides a physical quantity sensor, comprising a protective cover, a sensing contact, a honeycomb frame, a signal converter, a transformer, a wind tower box, a high pole frame and an induction chip, and the protective cover is arranged on the upper part of the honeycomb frame; The induction probe is installed in each small hole on the honeycomb frame; the signal converter is arranged in the wind tower box. In the present invention, the wind force is felt through the force-bearing film, so that the shape of the force-bearing film changes, and then the distance from the capacitor plate changes, thereby changing the capacitance of the entire sensing contact, and then measured by the voltmeter in the signal converter. The voltage is transmitted to the induction chip through the information output line, so as to calculate the size of the wind force. Due to the setting of the honeycomb frame, you can feel the different winds around you, so you can know the wind direction according to the source of the signal. Many sensors in the honeycomb frame Contacts can also effectively avoid the occurrence of accidents and greatly improve the reliability of the results.

Description

technical field [0001] The invention belongs to the field of sensor manufacturing, in particular to a physical quantity sensor. Background technique [0002] At present, people pay more and more attention to the change of weather, and the change of wind force is closely related to people. The wind can bring us rain and remove smog. Most of the current wind measuring devices are placed on high mountains, and the wind speed is determined by the speed of the wheels. Size, simple and effective solution to people's problems, but as people's living requirements increase, the requirements for the information obtained in the world they live in are higher, and the existing anemometer devices are not so accurate and cannot be obtained in real time the direction of the wind. [0003] Therefore, it is very necessary to invent a physical quantity sensor. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention provides a physi...
