An apparatus for cultivating plants may include a cabinet forming a space in which plants are cultivated; a door connected to the cabinet to open and close the space; at least one bed disposed in the space and configured to support at least one seed package accommodating a medium including seeds; and at least one light assembly that radiates light to the at least one seed package on the at least one bed. The light assembly may include at least one LED module including a plurality of LED groups; a light case that covers an upper portion of the at least one LED module; and a light cover coupled to the light cover and supporting a lower portion of the at least one LED module.

Apparatus for cultivating plants

A VOC detection sensor includes: a photoemission acceleration unit including a first electrode and a second electrode spaced apart from each other to face each other and a power source unit forming an electric field between the first electrode and the second electrode, photoemission means disposed within a space formed by the first electrode and second electrode of the photoemission acceleration unit and emitting photoelectrons, a light source supplying light energy by which the photoemission means emits photoelectrons, and an ammeter measuring the amount of charges flowing between the first electrode and the second electrode, wherein VOCs in the space between the first electrode and the second electrode are ionized through a collision against photoelectrons accelerated by the photoemission acceleration unit, and the ammeter detects a concentration of the VOCs by measuring the amount of charges formed by the ionized VOCs between the first electrode and the second electrode.
