Published on Nov 30, 2023


This system automatically send SMS to customer for EB, Phone bill cost of each two Months using GSM and auto billing with SMS reply systems. The system will work as a Auto billing for all.

1) PC interface system:

This is divided into two different modules,

a) Serial Communication

b) Data Base

c) SMS using Fbus cable

2) PC:

This is divided into three modules

a) RS232 communication,

b) Display module

c) Data Base Storage System

3) GSM

This system is used to read and control the data from all four machines. Then for each day all data’s are sending into PC via RF communication. The PC will receive all data and display on the screen and stored in DB using C. At the same time the controller will send the data (Status) into owner mobile via GSM communication.
