I’m using a 1 gram strain Gage (it came out of a Chinese product). It is used for measuring US money, which weights 1 gram per banknote. I am running the signals to a solder board and then to a breadboard using 22 Gage wires to a INA125P. The problem i’m getting is that the scale seems to fluctuate too much even when I try smooth the signal in software by taking the last 4 readings.
I want to replicate the same thing. As USD currency weighting scale.
My signals look something like this:
141, 142, 141, 142, 141, 142, 141, 142.
My question is, is this normal? Can anyone recommend if this is normal or is the anyway to improve it.
