The invention relates to the technical field of pressure sensors, in particular to an unmanned aerial vehicle airborne pressure sensor which comprises a bottom plate and a shell arranged on the upper surface of the bottom plate, and the upper surface of the bottom plate is provided with an air pressure sensor, a temperature sensor and a microprocessor which are located in the shell and further comprises an annular plate and a connecting assembly. The annular plate is arranged on the upper surface of the bottom plate, the shell is rotationally arranged in the annular plate and rotationally connected with the bottom plate through a connecting assembly, the shell comprises an inner shell and an outer shell which are connected in a sleeved mode, the inner shell is fixedly arranged on the upper surface of the bottom plate, and two air holes are formed in the top of the inner shell. According to the invention, the black sponge can be driven to rotate, so that the air pressure sensor can automatically adjust the shielding thickness of the black sponge to the air holes when encountering air flows with different intensities in the flight process of the multi-rotor unmanned aerial vehicle, thereby ensuring the detection precision of the air pressure sensor, and further ensuring the flight control precision of the multi-rotor unmanned aerial vehicle.

    本发明涉及压力传感器技术领域,具体为一种无人机机载压力传感器,包括底板和设置于底板上表面的壳体,所述底板的上表面设置有位于壳体内部的气压传感器、温度传感器和微处理器,还包括环形板和连接组件,所述环形板设置于底板的上表面,所述壳体转动设置于环形板的内部并通过连接组件与底板转动连接,所述壳体包括套接的内壳和外壳,所述内壳固定设置于底板的上表面且顶部开设有两个气孔。本发明能够驱动黑色海绵旋转,使气压传感器在多旋翼无人机飞行的过程中遇到不同强度的气流时,自动调整黑色海绵对气孔的遮挡厚度,从而能够保证气压传感器的检测精度,进而保证多旋翼无人机的飞行控制精度。
