Problems solved by technology

The principle of the device is simple, and its disadvantages: the size of the sensor is not considered, the debugging and installation of the sensor are cumbersome, and it is not convenient to carry; in addition, the diversification of the communication interface is not considered, the communication interface is single, the use conditions are relatively harsh, and it is not widely used. Applicability
[0006] All of the above existing technologies have the defect of inaccurate sensor detection information. At the same time, the sensor unit is not compact in structure, occupies a large space, and is not conducive to carrying. Therefore, it is necessary to propose a new sensor system for the detection of meteorological information.
