Strain gage for weight measurement?

recently, my group is working on a project based on strain gage device to measure the weight of tiny staff.but we do not know too much about how the strain gage works?and we use the voltage output to calculate the weight ,then display that on a LCD.there also is a bounch of push buttons to control the power and the scale interchange between lb and kg.we do need help on the schematics of those parts,as well as the software!!

The weight of a tiny staff? IS this the only thing it has to weigh? How much does a tiny staff typically weigh?
Try https://www.google.com
Search for "strain gauge circuit schematic" for lots of interface examples.
Then you need an A/D to provide digital weight data. Then you need a microcontroller for scaling the data and LCD display functions.. Thats about it.
 
You will find all strain gauges are of a differential type. You will need either a fully differential ADC (simplest solution), or an instrumentation amplifier between the strain gauge and the ADC.
