Fuente: WIPO "organic farming" The utility model relates to an organic farm air humidity monitoring device which comprises a base, a containing cavity is formed in the base, a motor is fixedly connected to the interior of the containing cavity, and the top of an output shaft of the motor penetrates through the base and is fixedly connected with a second gear. A base is moved to a corresponding detection position of an organic farm, an output shaft of a motor drives a second gear to rotate, the second gear drives a first gear to rotate, the first gear drives a rotating column to rotate, the rotating column drives a supporting plate to rotate, the supporting plate drives an L-shaped plate to rotate, and the L-shaped plate drives an air humidity sensor to rotate. Furthermore, the piston rod of the hydraulic cylinder drives the connecting rod to rotate, and the air humidity sensor can detect the air humidity of the surrounding environment in all directions at any angle, so that the purposes of accurately detecting the air humidity in all directions at any angle in the organic farm and reducing the detection error are achieved.
