The invention discloses an intelligent agricultural multi-parameter acquisition device and method based on 5G. The device comprises a mounting plate, a mounting opening is formed in the outer wall ofthe top of the mounting plate, an inserting cylinder is fixedly connected to the inner wall of the mounting opening, a movable column is arranged in the inserting cylinder, and a soil pH value sensoris arranged at the bottom end of the movable column; a through hole is formed in the outer wall of the bottom of the inserting cylinder, a monitoring mechanism is arranged on the outer wall of the topof the mounting plate, a fixing mechanism is arranged on the inserting cylinder, limiting rings are fixedly connected to the positions, close to the top and the bottom, of the inner wall of the inserting cylinder, and the movable column is arranged in the limiting rings in a sliding mode; the monitoring mechanism comprises a rotating rod, fan blades, a displacement sensor and an encoder. The device is simple in structure, parameters such as the wind speed and the wind direction are quite convenient to collect, the inserting rods on the sliding plate can be moved out of the fixing openings andinserted into soil around the inserting cylinders, and the whole device is more stable.
