Your browser does not support the video tag. In the time-lapse video, we can clearly see how a lemon tree wilts due to a lack of water and then perks back up after being watered. The time-lapse is not only beautiful to watch, but also serves as part of a series of experiments. The tree is equipped with sensors. This allows us to observe the relationship between what we […]

The city of Schorndorf aims to make the maintenance of its urban trees increasingly digital and data-driven. In the future, technologies such as GPS-assisted route planning and AI-based software will help organize workflows more efficiently and allocate resources more effectively. The use of TreeSense sensors to monitor water requirements and tree health marks the first step in this direction. Project Overview As part of the […]

The FDR sensor is a sensor used to determine the volumetric water content in the soil. FDR stands for Frequency Domain Reflectometry. The sensor measures the soil’s ability to store electrical charge and uses this to determine the water content. What is charge storage capacity? Capacitors are used to store electrical charge. A capacitor consists of two conductors […]

Prerequisites: TreeSense Pulse: Electrical Resistance Measurement Explained A brief recap of resistance measurement in the Pulse Sensor Electrical resistance (measured between two conductive screws in the xylem) is a strong indicator of moisture content in the branch. Simply put: dry wood has high resistance, while moist wood has low resistance. However, resistance is also influenced by temperature and tree species-specific […]
