Automatic measurement system for water stress of plants, particularly trees has microcontroller serving as core of system, and which amplifies, outputs and stores

摘要

An electromechanical sensor detects the water stress of plants by measuring the curvature of a metallic sensitive component that is placed around the trunk or branch of a plant comprising a structure having a base formed by tweezers. The structure is formed by two rectangular pieces of aluminum with one semi-circular corner. A microcontroller that amplifies, outputs and stores serves as the core of the system.
