Strain Gauge Bending detection Sensor Module

The Strain Gauge Bending Detection Sensor Module is a high-precision measurement module designed to detect mechanical deformation, bending force, strain, and pressure variations in structures and mechanical systems. The module is based on the BF350-3AA precision strain gauge sensor, which uses constantan metal foil resistance technology for accurate and stable measurements.

The sensor includes an onboard signal amplifier and adjustable potentiometer, allowing users to calibrate and fine-tune the output according to application requirements. It produces an analog voltage output proportional to the applied strain or deformation force.

The BF350-3AA strain gauge features excellent temperature compensation, low creep characteristics, high sensitivity, and stable long-term performance. Its compact design and Arduino compatibility make it suitable for educational, industrial, and research projects.

This module can be used for structural monitoring, load detection, force sensing, bending measurement, robotics, automation systems, and engineering analysis applications.
