Load cell bathroom scale.

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. 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. Next we will explore calibration and test the load cell as a weighing scale. 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. Three wire load sensors from a bathroom scale. 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. This gives me two opposing wheatstones.

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. Therefore four load cells are used and their outputs are summed appropriately. Whereas analog scales use springs to indicate the weight of an object digital scales convert the force of a weight to an electric signal.

Digital scales work with the use of a strain gauge load cell. Load cell usage load cell using 3 wire load sensor https.
