Abstract: The present invention discloses an air conditioner control device, air conditioning system, and air conditioner control method. The air conditioner control device of the present invention comprises a base and a controller. The base senses a temperature or humidity of a first environment. The controller can be optionally combined with or detached from the base. When the controller is detached from the base, the controller senses a temperature or humidity of a second environment and communicates with the base using a wireless network protocol. By doing so, the output of an air conditioner can be flexibly adjusted depending on the environment that a user is in.
