PiCUS TMS – Tree Motion Sensor

The wind reaction measurement of the TreeMotion Sensor records the swinging movement of trees under real conditions and allows conclusions to be drawn about the anchoring of the roots in the ground. In addition to the properties of the tree, all factors influencing the environment on the wind are taken into account. This allows the stability to be assessed in the actual wind exposure.

A base sensor directly measures the root plate inclination at the base of the trunk. A control sensor measures the inclination at a height of 2 to 3 meters so that the real wind reaction of the tree can be distinguished from sources of interference. The PiCUS TreeMotion Sensor can independently record the measurement for hours, days or weeks. The data evaluation takes place comfortably in the office.

Prerequisites for a successful measurement are gusts of more than 45 km/h and a measurement time of at least 2 hours.

Analyze entire groups of trees at once

Compare the slope values of several neighboring trees, to efficiently identify individual endangered trees.

Fast and with little effort

A good application of the TreeMotion Sensor is the comparative analysis of groups of trees. Several trees are equipped with sensors at the same time before an expected storm. For example, all trees in an avenue can be tested very quickly with little effort.
