1. A plant cultivation apparatus comprising:
a cabinet defining a cultivation chamber in which a plurality of beds are accommodated;
a sensor positioned in a lower portion of the beds and configured to detect liquid on the plurality of beds;
a liquid supply module provided in the cultivation chamber and configured to supply liquid to at least one of the plurality of beds; and
a controller configured to:
determine when to supply liquid to the plurality of beds,
determine, based on information collected by the sensor, whether liquid is present in the plurality of beds in response to determining to supply liquid to the plurality of beds, and
sequentially perform a liquid supply operation to one or more beds, of the plurality of beds, in which liquid is not present,
wherein the controller, when sequentially performing the liquid supply operation, is further to:
manage the liquid supply module to supply a predetermined amount of liquid to a bed of the one or more beds,
count a number of times that the liquid supply module liquid-supplies liquid to the bed, and
manage the liquid supply module to wait for a delay time before again supplying liquid to the bed,
wherein the bed has a depression which is formed to be recessed from an inner bottom of the bed to receive and store liquid from the liquid supply module,
wherein the bed is formed with a sensing protrusion which protrudes from a bottom surface of the depression, the sensing protrusion having an upper surface positioned higher than the bottom surface of the depression and lower than a bottom surface of the bed, and
wherein the sensor detects whether residual liquid is present on the upper surface of the sensing protrusion.
