Relating measuring the wieght !!!

[hassan1980]

Hi, guys

By the way, I want to make a project for measuring weight using PIC Microcontroller but I need your advice for choosing the sensor for the weight

I am waiting your reply

Use load cell with amplifier
It is a bridge of 2 thin wire resistors , one of them mounted on a deformable billet ,the other one to sense and compensate for the temperature variation.
and 2 other resistors
The bridge is fed by a dc volatge and the
2 other sides are amplified and the result properly formatted is the weight.
You shoud see to google load cell and get much more info that I can give you.

use AD7730 from www.analog.com

it is loadcell to digital

HI

See Zilog site nice application for load cell using the Z8 - code written in C and it can be ported to allmost any micro


All the best
