Sparkfun tutorials load cell.

You may not need everything though depending on what you have. If you are hooking together four of the sparkfun load sensors using the combinator board you should position the four load sensors equidistant from each other just like the bathroom scales shown in this tutorial. Overview the sparkfun openscale makes reading load cells easy. To learn more about load cells see our tutorial on getting started with load cells.

This tutorial is here to help you get started in the world of load cells and their variants. Attach a four wire or five wire load cell of any capacity plug openscale into a usb port open a terminal window at 9600bps and you ll immediately see mass readings. So i have purchased the sparkfun load cell amplifier and this board is a world of difference in other words works perfect this board is repeatable accurate steady no false resets and i like the separate voltage input to the load cell this gives me a full 5 vdc to the load cell for better resolution. It uses an esp32 thing to read load cell data from an hx711 load cell amplifier and display that data on a serial 7 segment display as well as posting it to a python based website that can be hosted locally or on the cloud.

One of many kinds of load cells. Sparkfun has carried a similar product the hx711 for years.

This is the original sparkfun tutorial system used for years for single page tutorials and a lot of other things like projects tear downs and buying guides.

Bit analog to digital converter is extremely precise and is designed to read the very small changes in voltage that a load cell or scale produce. To follow this project you would will need the following materials.
