OBJECTIVE

To measure and monitor the ingredients of batching

plant and analyze the strength of the product.

ABSTRACT

In this system, the scanner is given multiple inputs using

various communication modules like RS 232, Bluetooth and

RF. It selects each input for a fixed time period. This data is

stored in RAM and is delivered using various communication

modules like RS 485, GPRS and RS 232 to the host PC ,

mobile and to the printing device.

INTRODUCTION

WHAT IS A SCANNER? An electronic device which records data over time via

external instruments.

It accepts multiple inputs , and transmits them to PC , single data at a time.
