A 20 kg strain gauge load cell with four wires, featuring a metallic foil gauge bonded with epoxy to a solid aluminium bar. The aluminium constrains deflection and protects the gauge from damage. Mount one end to a fixed surface using the mounting holes, then apply force to the other end in the direction indicated on the label.
The output resistance changes proportionally with applied force and is measured using a precision ADC or Wheatstone bridge circuit (such as the HX711 load cell amplifier).

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Strain gauge
- A sensor element that changes resistance when it is stretched or compressed. It is commonly used for measuring force, weight, or bending, and often needs precise differential measurement electronics like this ADC.
