Load cell bathroom scale.

Endgroup dave tweed mar 7 14 at 16 45. Arduino this design uses a standard arduino uno other arduino versions or clones should work also hx711 on breakout boa. Digital scales work with the use of a strain gauge load cell. Next we will explore calibration and test the load cell as a weighing scale.

Arduino bathroom scale with 50 kg load cells and hx711 amplifier. Therefore four load cells are used and their outputs are summed appropriately. Three wire load sensors from a bathroom scale. Load cell usage load cell using 3 wire load sensor https.

This gives me two opposing wheatstones. 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. An update to the previous 50kg bathroom scale load cells tutorial. 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.

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. This instructable describes how to make a weighing scale using readily available off the shelf parts materials needed.
