1. An air state detection floating device capable of remaining in air, which comprises:
a case composed of a first case, a second case, and a third case,
wherein,
the first case includes:
an upper portion including a top surface;
a lower portion including a bottom surface;
a power supply unit;
at least one memory for storing instructions;
at least one processor;
a communication unit for transmitting and receiving data;
a first sensing unit for detecting information on an air state of an enclosed space, wherein the first sensing unit is attachable to and detachable from the first case; and
a second sensing unit for generating location information,
the second case has a hemispherical shape,
the second case comprises an upper surface and a lower surface, wherein the upper surface of the second case has a planar region coupled to the bottom surface of the first case such that the second case supports the bottom surface of the first case, and the lower surface of the second case is a curved surface,
the third case has a spherical shape configured to surround the first case and the second case,
the third case comprises a first portion and a second portion, the second portion of the third case including a lower curved surface coupled to the curved surface of the second case,
the first portion of the third case is coupled to the upper portion of the first case,
the second portion of the third case is coupled to the lower portion of the first case,
the second case includes a buoyancy supply unit for providing buoyancy to the first to the third cases,
a driving unit for generating a driving force is disposed at the second portion of the third case,
a space is formed between the first portion of the third case and the second portion of the third case in an upper area of the first case, and the space is configured to allow a fluid to travel,
an air suction cover and an air exhaust cover are disposed at a region of the space so as to open or close the space and each of the air suction cover and the air exhaust cover is connected to the driving unit,
the instructions are executable by the processor such that the processor performs operations,
the operations comprise an operation that generates a control signal for movement in an enclosed space based on the data; and
an operation that controls the driving unit based on the control signal such that the air suction cover and the air exhaust cover open or close the space.
