Load Cell 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.

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. Arduino this design uses a standard arduino uno other arduino versions or clones should work also hx711 on breakout boa. 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. Whereas analog scales use springs to indicate the weight of an object digital scales convert the force of a weight to an electric signal.

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. 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.

Therefore four load cells are used and their outputs are summed appropriately. An update to the previous 50kg bathroom scale load cells tutorial. Next we will explore calibration and test the load cell as a weighing scale.
