This significantly reduces the manufacturing cost of the universal sensor, significantly expanding its application range.

[0032] According to the present embodiment of the invention, the universal sensor uses an integral mounting structure consisting of the ball and the universal base, eliminating the need for a magnetic mounting structure. As a result, the universal sensor is less susceptible to theft or damage. This allows the user to safely install the universal sensor outdoors, better meeting practical requirements in use.

As a result, this structural design allows a press fit to be achieved between both the inner and outer walls of the rotatable mounting seat, resulting in a stable connection between the sensor assembly and the universal base. The universal sensor thus offers greater structural stability.

[0034] Furthermore, according to the present embodiment of the invention, the outer wall of the rotatable mounting seat has an external thread, while the inner wall of the mounting cap is provided with an internal thread. Thus, the user can connect the universal base to the sensor assembly by simply rotating the mounting cap, without requiring specialized personnel.
