This is a Strain Gauge Bending Sensor Module Y3 Weighing Amplifier Module.

A strain gauge is a device used to measure strain on an object. This strain gauge module uses the strain gauge BF350-3AA, it has an onboard amplifier and potentiometer to adjust the measured results

A Strain gauge is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured

A strain gauge works on the principle of electrical conductance and its dependence on the conductor’s geometry. Whenever a conductor is stretched within the limits of its elasticity, it doesn’t break but, gets narrower and longer.


  1. Two tubes of reverse protection ~ (to prevent the power supply from connected to the back)
  2. On board with a blue LED power indicator
  3. Analog output
  4. The higher the bending degree, the higher the output voltage
  5. Zero potentiometer
  6. Can be used to adjust the output voltage of the starting voltage
