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. Learn what is load cell, types of load cells and how a load cell works? Upload the main code to measure weight.

Dec 18, 2020 · With the right components and setup, this type of amplifier circuit can provide accurate and reliable results in a variety of applications. Weighing Machine Using Arduino Load Cell Hx711 Module. Connecting Hx711 Load Cell To Arduino Tutorial Nerdytechy. Load Cell Amplifier Hx711 Breakout Guide Learn Sparkfun Com.

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.

The easiest way to get a weigh reading from these to an Arduino is to use the HX711 amplifier module. It reads the tiny voltage change inside the load cell and turns it into a 24bit digital numeric value that can be interpreted by the Arduino as a weight value. Required Components.
