Hi Dear,
I am an expert with more than 10 year of experience in the field of embedded systems, programming, electronics and signal processing. I have worked on architectures like 8051, PIC, AVR, MSP430 and ST. I have hands on experience in fields of smart metering, GSM/GPRS based meter communication and RF communication.
I have checked the details of your project and happy to learn that I can help you in developing a low cost, small form factor and reliable product for you. In addition to this, I have been to china many times and I have contacts with suppliers that can help us make a low cost product. The idea is to have the following parts.
Electronic load cell (as a linear sensor to the weighing machine)
A local display unit (LCD or LED).
Low cost GSM module (may be SIM900)
MCU to control the overall function
The terminal software (working as a server) to be able to collect data from GPRS (internet) or SMS
* We can use SIM548 which is a GSM/GPRS/GPS module to locate the position of our weighing scale.
I have all the development tools related to MCU and I would source the parts my self. I would deliver you 2 working prototype boards within 30 days along with complete Schematics, PCB layouts, Source codes and PC Software (if required)
Regards
Chaudhry
