US Patent 11343976 Indoor garden center with a plant pod detection system

An indoor gardening appliance includes a liner defining a grow chamber and a grow module mounted within the grow chamber for receiving a plurality of plant pods. The grow module defines a root chamber and a plurality of apertures for positioning a root end of the plant pod in the root chamber. A resonator may be positioned on each plant pod or at each of the plurality of apertures for generating a unique sound signature when a specific plant pod is inserted into a specific aperture. A detection device, such as a microphone, measures the sound waves generated by the resonator and a controller determines a location and/or a type of the plant pod based on the unique sound signature.
