Abstract: A plant measurement system is arranged to monitor plant and/or plant organ movements in real-time and relies on small scale digital sensor technology. The sensor is foreseen of an affixing means easily attached to a plant or plant organ to capture dynamic plant movements. The sensor module can be integrated in large plant monitoring setups and has wireless capabilities, enabling the use in remote locations. The system determines the orientation of its sensors to assess movements over time and can process the digital data of multiple sensor modules in real-time. These data are readily available for visualization of continuous plant and/or plant organ movements. The system can be applied for monitoring plant development, stress responses and adaptation responses to internal and external stimuli. Real-time plant information is provided to detect stress conditions and enable precise environmental control.
