Load Cell Bathroom Scale

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.

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. Digital scales work with the use of a strain gauge load cell. Whereas analog scales use springs to indicate the weight of an object digital scales convert the force of a weight to an electric signal. An update to the previous 50kg bathroom scale load cells tutorial.

Arduino this design uses a standard arduino uno other arduino versions or clones should work also hx711 on breakout boa. Endgroup dave tweed mar 7 14 at 16 45. This instructable describes how to make a weighing scale using readily available off the shelf parts materials needed. 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.

Load cell usage load cell using 3 wire load sensor https. 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.

The total weight on a bathroom scale is the sum of the weights on each support which are not necessarily equal and four supports are used for maximum stability when stepping on or off the scale. This gives me two opposing wheatstones.
