I'm having difficulties interfacing load cell with 2mV/V fidelity :(
Can anybody suggest me how am i supposed to interface the small amount of electric changes of the load cell into something that my AVR ATMEGA8535 read? From what i've search from the net, 2mV/V fidelity gives you 10mV output on full load capacity with 5V voltage source (my load cell max load is 200kg)
I'm thinking using opamp OP07. Is that enough? :0

Sorry, i posted it on the wrong section

The best way of interfacing of a load cell to a microprocessor is using Instrumental Amplifier (AI) or any other kind of signal conditioning task.also you can use comercial packages like ADAM 3016 from ADVANTECH.
