Thanks for taking the time to reply. I want to prototype an idea I have
and
if the idea truns out to be a good one then perhaps go into low volume
production. My problem is that I am a computer programmer not an
electrical
engineer. So I am trying to find low cost components that I can assemble
on
a bread board for a prototype.
I did find this at
http://www.alibaba.com/product-gs/205545588/Micro_weight_Style.html?pn=6&pt=10&total=31&cids=10101838,50146584,50136352,200011188,50139365,50136805,200016031,50133357,200007460,50014385,50018800,50023060,50134883,50146124,200000970,&tracelog=detailtop12907&newId=205545910#page960
Model CZL902
===========
Rated load: 50KG
rated output: 1.0+-0.15MV/V
dimensions: 34*34*7.8(mm)
Cable spec: 0.8*420mm
To my simple non-ee mind it looks like this might be useable out of the
box.
I am hoping to find one I that I can just read the voltage and then
compute
the weight.
