The invention relates to the technical field of sensors, and particularly discloses a temperature and humidity pressure sensor core, a sensor and a packaging method, and the core comprises a shell structure which is provided with a medium flow channel along the axis direction; the composite sintering seat is connected to one end of the shell structure and comprises a metal base and a conductive needle; the metal base is provided with a containing cavity in the axis direction and a pressure guide hole spaced from the containing cavity, and the conductive needle penetrates through the containing cavity in the axis direction and is fixed based on the sintering technology. Wherein a sintered body for sealing the accommodating cavity is sintered in the accommodating cavity, and two ends of the conductive needle respectively protrude out of the end surfaces of the metal base and the shell structure; the main conditioning circuit board covers the end face of the metal base and is electrically connected with the conductive needles; the pressure sensing chip is arranged on the metal base and blocks one end of the pressure guide hole; the temperature and humidity sensing component is electrically connected with the conductive needle away from the main conditioning circuit board, the sensor is compact in structure, the sealing performance is improved, and the sensor can stably operate under the working conditions of continuous vibration, high temperature and high pressure.

This utility model relates to the field of wireless target ranging technology, and discloses a non-contact wireless target ranging device, including a power supply box. A support plate is fixedly connected to the bottom left side of the power supply box. A groove is formed on the top right side of the support plate. A second protective box is fixedly connected to the top of the support plate. A movable baffle is slidably connected to the left side inside the second protective box. An energy block is fixedly connected to the top left side of the power supply box. A guide tube is fixedly connected to the left side of the energy block. The bottom of the energy block is fixedly connected inside the groove. A laser port is fixedly connected to the left side of the guide tube. In this utility model, the protective structure formed by the second protective box and the movable baffle can effectively block the intrusion of harmful gases, protect internal components, and, combined with a sealed design, resist the influence of extreme environments on the device, ensuring that signal transmission is not interfered with, and achieving high-precision measurement requirements in complex environments.
