Y3 Strain Gauge Weighing Sensor Amplifier Module – Bending/Load Sensor

The Y3 Strain Gauge Weighing Sensor Amplifier Module – Bending/Load Sensor integrates a BF350-3AA metallic foil strain gauge and a 3peak amplifier on a single compact PCB combining two components that engineers typically wire separately into one ready-to-connect module. The BF350 gauge at 350 ohms produces resistance changes in the milliohm range under mechanical load – far too small for a standard Arduino ADC to measure directly. The onboard amplifier takes that tiny resistance change, converts it through the Wheatstone bridge configuration on the PCB, and outputs a measurable analog voltage.

The y3 strain gauge sensor amplifier module sensitivity factor of 2 means a 1% strain produces approximately 2% change in gauge resistance – the standard gauge factor for metallic foil gauges. Strain limit of 0.02 means accurate measurement up to 2% deformation of the bonded surface before the gauge enters its nonlinear range. The module operates at 5V, connecting directly to Arduino 5V power and analog input pins without external regulation.

The strain gauge bending sensor module y3 suits custom load cell fabrication where a standard beam or cantilever forms the mechanical element and this module provides the sensing and amplification in one step. Mounting the gauge 90° to the strain direction produces near-zero output regardless of applied load. This Y3 strain gauge sensor amplifier module available on StemVolt, and its measure for force measurement and load sensing.
