Hi,

I'm making a scale that has two pressure points, so i was thinking of using two strain gauges. the value of these will be converted into kg and displayed on a small lcd display.
the weight range will be 0-30kg with an error margin of +-50gram

can anyone tell me what i need as far as various components and software/hardware i need to program them?

thanks.
Frank

First find your strain gauges.

Then determine how to amplify the signal, convert it to digital, zero out the errors, convert to grams, and finally display it.

I would say that most of those steps (other than the first and the last) could be done with a microcontroller.
