After finding a broken scale in the trash at work, I decided to remove the load cell and build a digital scale with an Arduino. The output can be monitored on the Serial monitor of Arduino IDE. HX711 amplifier + load cell gives me an unstable result I finally finished hooking up my HX711 amplifier to my arduino uno and the load cell (taken out of a kitchen scale) My code is … !Connection to an Arduino + Base Board Uno. In this primer I’m going to describe how to interface one inexpensive Load Cell to an Arduino Uno with the help of the popular HX711 module so that you can rig up a complete digital weight scale later. HX711 AD Module: BHX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The arduino based layout of the project is shown in figure 1. Description: HX711 and Arduino-This tutorial is based on the HX711 breakout board, Arduino Uno and a Load cell or Strain gauge.This tutorial explains step by step how to use the load cell or Strain gauge with the HX711 breakout board and how to write a basic Arduino Uno program to access the values and print them on the Serial monitor. 16×2 Alphanumeric LCD x 1.
