PLANT COMMUNICATION DEVICE

摘要

To achieve communication with a plant certainly and practically. The plant communication device comprises a first electrode (40) attached to any one of a plant (10), gardening soil (20) and a container (30), a high frequency power supply (50) for applying a high frequency voltage to the first electrode (40), a second electrode (60) for grounding the ground side of the high frequency power supply (50), a detection means (70a) connected between the second electrode (60) and the high frequency power supply (50), and a load control means (80) for operating a load (90), wherein the detection means (70a) detects a variation in returning current between when a human body approaches or touches the plant (10) and when the human body does not, and the load control means (80) operates the load (90) when the human body approaches or touches the plant (10).
