Adafruit Strain Gauge Load Cell - 4 Wires - 5Kg

A strain gauge is a type of electronic sensor used to measure force or strain. They consist of an insulating flexible backing with a metallic foil pattern. When force is applied, the resistance of a strain gauge changes as the object and foil are deformed, resulting in a different electrical output.

This gauge is protected by a strong aluminum chunk to prevent damage and limit movement. Secure one side to a fixed enclosure or ground using the mounting holes, ensuring stability. Apply weight to the other side in the indicated direction, either by gravity or pulling, to measure the change in resistance.

The output resistance changes with deflection and is measured with a precision ADC or Wheatstone bridge. Useful for measuring pressure, force, weight, and tension, this is a 5 Kg strain gauge. Note that an ADC or converter is not included. Calibration with known weights is required once installed.

Available in 1 Kg, 10 Kg, and 20 Kg variants, ensure to choose one with at least twice the maximum force or weight for optimal precision within the appropriate range.
