PiCUS Tree Motion Sensor

The Wind-Reaction-Measurement with PiCUS TMS is used for in depth tree inspections to obtain information about a tree’s stability in a live situation, defined by its root anchoring force in the ground.

This technique is called Tree Motion Sensor (TMS) and can be used on trees with suspicion of reduced stability. Causes of reduced stability may be fungi or root damage occured in conjuction with excavation in the root zone. Surveillance of such trees over a longer period may display changes in stability. TMS can be used to monitor both singular trees and whole groups.

TMS is a small electronic device that measures the dynamic movement in the root collar ('dynamic root plate tilt') 20 times per second. Measurements are as accurate as 0,01°. TMS is a dynamic measuring system that records live. Sensors are solid and easy to install.
