Detection module, interface systems and method for detecting interactions of a user with a living plant and communicating control signals

An interface system for communicating control signals to one or more electronic devices, the interface system comprising:

• One or more detection modules for detecting capacitance variations in one or more plants, comprising:
• one or more electrodes configured and arranged to be put in electrical communication with the plant;
• one or more capacitive sensors in electrical communication with the one or more electrodes, and configured to measure capacitance through the one or more electrodes and output voltage values;
• and
• a control unit in electrical communication with one of the one more capacitive sensors, the control unit having at least one communication port connectable to one of the one or more detection modules or to one or more external devices, the control unit being configured to
• receive said voltage values,
• process the received voltage values and obtain processed voltage values,
• compare said processed voltage values with a threshold value, and
• send a control signal to the one or more external devices via said at least one communication port when said processed voltage values exceed the threshold value;
• and
• a user-accessible potentiometer in electrical communication with the control unit, the potentiometer being configured to adjust said threshold value,
• wherein each of said one or more detection modules is configured for electrical communication with each of the one or more plants, and
• wherein the one or more plants are of a crass kind.
