Sparkfun Load Cell Combinator

This is the same layout that you would find in say your home scale.

Sparkfun load cell combinator.

Sparkfun s strain gauge load cell combinator board hooked up to a home scale possible four disc load cell configuration in something like a bathroom scale note. This version of the sparkfun load sensor combinator features a few changes that you specifically asked for. Sparkfun load cell amplifier hx711. Sparkfun load sensor combinator bob 13878 1 95.

We created the load cell combinator to make this a lot easier. Sparkfun load cell amplifier hx711 sen 13879. There would be four single strain gauge load cells hooked up to a combinator and an amplifier to give you your weight reading. These often use four individual cells that need to be combined into one complete load cell.

By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you ll be able to get very accurate weight measurements. The sparkfun load sensor combinator is a bare pcb that combines four load sensors into a standard four wire wheatstone bridge configuration if you open up an electronic bathroom scale you ll find a large rat s nest of wires. Once you have your combinator in place you should have the four wires red black white green coming out of the combinator ready to connect to qwiic scale.
