Hi!
For my masters thesis i have to develop a scaled helicopter test bench. To test te lift force of the helicopter I use load cells. I found a solution online to make a load cell circuit with an arduino to process the measured forces. Everything works, but the precision of the circuit isn’t good enough.
In picture 1 you can see the circuit I used.
For a load of 20 kg I should get a value of 1023 after the arduino A/D converter. The maximum value I can get is 864.
So now I have a few...
