1. A sterilization apparatus, comprising:
a housing forming a sterilization space;
a first sterilizer configured to radiate plasma rays toward the sterilization space;
a second sterilizer configured to radiate ultraviolet light toward the sterilization space;
a sensing unit configured to sense whether an object is placed in the sterilization space; and
a controller configured to control an operation of the second sterilizer based on information sensed by the sensing unit;
wherein the controller is configured to,
while the plasma ray is radiated toward the sterilization space,
operate the second sterilizer to radiate the ultraviolet light toward the object in response to sensing that the object is brought into the sterilization space.
