Its key components consist of a strain gauge a device used to measure the strain of an object and load cell sensor an electronic device used.
Load cell bathroom scale.
This instructable describes how to make a weighing scale using readily available off the shelf parts materials needed.
This gives me two opposing wheatstones.
Three wire load sensors from a bathroom scale.
Arduino bathroom scale with 50 kg load cells and hx711 amplifier.
Degraw 5kg load cell and hx711 combo pack kit load cell amplifier adc weight sensor for arduino scale everything needed for accurate force measurement onyehn 4pcs 50kg human scale load cell resistance half bridge amplifier strain weight sensor with 1pcs hx711 ad weight module for arduino diy electronic scale.
Next we will explore calibration and test the load cell as a weighing scale.
50kg load cell this load sensor sometimes called a strain gauge is the same one found in digital bathroom scales you know the ones you use in january for your new year s resolutions and then forget about a month later.
Digital scales work with the use of a strain gauge load cell.
Load cell usage load cell using 3 wire load sensor https.
Whereas analog scales use springs to indicate the weight of an object digital scales convert the force of a weight to an electric signal.
Therefore four load cells are used and their outputs are summed appropriately.
I ve wired them as if they were each 1 2 wheatstone bridge using the red wires as the signal with back vss white vdd 3 3v.

The load cell must also be accurately wired to the hx711 to ensure that the appropriate strain gauge leads are used to approximate the weight given by the load cell.
