Tilt sensor based on NB-IOT

The utility model relates to the technical field of inclination sensors, in particular to an NB-IOT-based inclination sensor, and solves the problem that in the prior art, when a cover plate needs to be opened for circuit board maintenance, the cover plate needs to be opened by rotating a plurality of screws, which is very inconvenient. The inclination sensor based on NB-IOT comprises a base and a sensor shell fixed on the upper end face of the base, and is characterized in that a circuit board is arranged in the sensor shell, a threaded hole is formed in the base, a connector lug is arranged on the side wall of the sensor shell, a cover plate is arranged on the upper side of the sensor shell, and a button is arranged on the cover plate. The cover plate is provided with a limiting part for realizing fixation between the sensor shell and the cover plate, and the inner wall of the sensor shell is provided with a guide part for guiding the cover plate. The cover plate can be disassembled without disassembling a
