Next try an unknown load.
Mini load cell arduino.
Wire the load cells and hx711.
Add calibrated mass equal to the variable y1 value above 20g in my case 5.
Grove adc for load cell hx711 the hx711 is a precision 24 bit analog to digital converter adc that is designed for weighing scales and industrial control applications to interface directly with a bridge sensor.
Wait for print out.
So once you have established two data pairs you can interpolate the rest.
The load should show properly.
Upload this sketch to your arduino board you need two loads of well know weight.
Restart program with nothing on the load cell platform 2.
Mini load cell 500g straight bar tal221 pdf mini load cell 100g straight bar tal221 pdf for more information about setting up load cells and how to integrate them into your next project check out our hx711 hookup guide.
In this example a 10 kg.
Edit the values of areading aload breading and bload with those values.
See the wiring diagram for how to connect the load cells hx711 and arduino.
It is specially made for amplifying signals from cells and reporting them to another microcontroller.
Wait for tare to finish and arduino to print out.
The aluminum load cell should have 4 tapped.
Arduino as load cell amplifier by christian liljedahl christian liljedahl dk load cells are linear.
Stack the load cell amplifier shield on top of the arduino board in our case a lynxmotion botboarduino.
Arduino scale with 5kg load cell and hx711 amplifier step 1.
The white connectors on the board are 4 pin molex connectors with 0 1 spacing.
Data is extracted from a 24 bit adc on board the hx 711 ic.
Add calibrated mass 4.
Reload the code to the arduino board and retest your known loads.
To connect the hx711 to the arduino you only need 2 pins clock and data.
This video will describe how to interface a 1 kg load cell to an arduino nano.
In this project we will be interfacing hx711 load cell amplifier with arduino and 16 2 lcd for designing arduino weighing machine using load cell hx711.
Stacking the load cell shield the load cell shield uses analog pins a0 and a1 for strain 1 and strain 2 inputs respectively.
Load the above code open the serial monitor and take measurements of two known loads.
Mount the load cell.
First we are going to mount the load cell.
We will be using a simple arduino library to communicate with the hx711 that provides a calibration and tare reset feature to easily determine the weight of an object.
