BF350 Strain Gauge Sensor Module


A strain gauge is a device used to measure strain on an object and the BF350 strain gauge sensor module is used to measure mechanical stresses in solid materials. This BF350 strain gauge sensor module contains an adjustable amplifier circuit to make it appropriate for interfacing directly to a microcontroller ADC input and needs only a single 5V power supply.

Features of BF350 Strain Gauge

  • Reverse protection diode ~ (to prevent power reversed)
  • Board with a blue LED power indicator
  • Analog Output: The higher the curvature, the greater the output voltage.
  • Output analog voltage: 0-3.5V
  • Board size: 32 X 17mm
  • Behind the printed board pin definitions (Bending strain gauge, you can change the output voltage)
