Abstract
A state sensor for plants comprises a clamping device with two clamping elements for clamping a part of a plant. A plant parameter measuring device is coupled mechanically to the clamping device and comprises a sensor element. Said sensor element is configured as a pressure sensor element arranged on one of the clamping elements for detecting a pressure state value of the plant, which pressure state value is independent of the displacement of the clamping elements relative to one another. A watering system has at least one state sensor of this type. A reliable determination of the watering state is obtained over a long period of time and at a low cost.
