In this tutorial we will see how to connect calibrate and display the weight on a small oled display and by using a rotary encoder we will be able to change the units from.
Diagram weight sensor arduino.
We will be using the hx711 adc converter board to amplify.
Arduino as load cell amplifier by christian liljedahl christian liljedahl dk load cells are linear.
Arduino bathroom scale with 50 kg load cells and hx711 amplifier.
In this project we will be interfacing hx711 load cell amplifier with arduino and 16 2 lcd for designing weighing machine using arduino load cell hx711 module.
Arduino this design uses a standard arduino uno other arduino versions or clones should work also hx711 on breakout boa.
Fritzing diagram of the load cell to the hx711 module.
Using a load cell or weight sensor you can add this capability to your arduino projects.
Today we are going to measure the weight by interfacing load cell and hx711 weight sensor with arduino.
Converter adc designed for weigh scales and industrial control applications to interface directly with a bridge sensor.
So once you have established two data pairs you can interpolate the rest.
We have seen weight machines at many shops where machine displays the weight just by placing any item on the weighing platform.
So here we are building the same weighing machine by using arduino and load cells having capacity of measuring.
Upload this sketch to your arduino board you need two loads of well know weight.
Here is the fritzing diagram.
This instructable describes how to make a weighing scale using readily available off the shelf parts materials needed.
The electronic weighing machine uses a load cell to measure the weight produced by the load here most load cells are following the method of a strain gauge.
Grams kg or pounds.
