Here I will go over all three connection diagrams: four-cell circuit, two-cell circuit, and a single cell circuit. This video is a detailed explanation of how to mount the bathroom scale load cell to a wooden board.

Nov 11, 2019 · On the first page you can see a block diagram. There are two pins DOUT and PD_SCK and a bracket saying To/From MCU. As the text says connect all clock to single line. In the source code above that is A0. Connect this to PD_SCK of all of your HX711. Then connect the DOUT pins separately.

Feb 7, 2020 · I am working on a project where I am setting up 10 load cells to measure the strength of elastics. I am using an Arduino Mega, 10x 300g Load Cells, 10x HX711 modules. I am able to wire everything up without issues and have successfully tested 1 Load cell at a time with bogde's HX711 library.

Attaching the Load Cell between Two Plates. Wiring the Load Cell to the HX711 Module and Arduino. Arduino Code to Read Weight Value from the HX711 Module. Testing the Scale. You can buy relatively cheap four-wire load cells from Banggood, eBay, or Aliexpress.

You can connect multiple load cells to the same Arduino by connecting each signal wire to a different analog input pin. Make sure to also connect the excitation and ground wires from each module to the appropriate power and ground pins on the Arduino.

Jan 25, 2025 · In this guide, you’ll learn how to create a digital scale with the Arduino using a load cell and the HX711 amplifier. First, you’ll learn how to wire the load cell and the HX711 amplifier to the Arduino to build a scale. Then, we’ll show you how to calibrate the scale, and a simple example to get the weight of objects.

Mar 3, 2014 · Hi there, I'm trying to use components found in a digital scale to interface with an Arduino in order to measure the weight of a human. After some research, I found that by using an INA125P amplifier I would be able to get an accurate reading from a load cell.

Nov 19, 2014 · See the wiring diagram for how to connect the load cells, HX711, and Arduino. On aluminum load cells, multiple strain gauges are already wired together to for a Wheatstone bridge. All you need to do is connect the wires to the HX711 board in the correct orientation. The HX711 library is available here: https://github.com/bogde/HX711.

Feb 7, 2022 · In this Arduino project, learn how to build a digital weighing scale by interfacing a load cell and its HX711 amplifier sensor with Arduino to measure the weight of an object and display the weight value on 16X2 LCD display module.

Aug 28, 2020 · How to program a Four Load Cell with HX711. I’m not going to write up a whole detailed article on how to do this as I have a YouTube video you can watch for the details. Overview. I have a project set up to monitor coffee levels in a carafe in my office. To accomplish this task, I used four load cells which I placed on mounts between two ...
