Amplifying the load cell s output voltage signal using a pre packaged instrumentation amplifier ic like the ina125 to be processed by the arduino s adc.
Tension load cell arduino.
That s exactly what the hx711 board does.
It is a second strain gauge with one in tension and one in compression when the base of the gauge is supported on the outer ring and force is applied on the center nib.
When these four strain gauges are set up in a wheatstone bridge formation it is easy to.
You can purchase one already made easy or you can take apart a cheap digital luggage scale and remove the load cell harder but you might already have one.
It worked and gave good results the first time i turned it on.
It reads the information from the load cell amplifies the signals and then sends it to the arduino for processing.

The hx711 and load cell are used in building a weighing scale.
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.
In bar strain gauge load cells the cell is set up in a z formations so that torque is applied to the bar and the four strain gauges on the cell will measure the bending distortion two measuring compression and two tension.
Load cell usage.
The two common approaches for interfacing a load cell with an arduino are.

The load cells plug into this board and this board tells the arduino what the load cells measure.
There are 2 options to get one of these.
Common load cells have four wire to connect the hx711 to a.
