The project 'Krishi Mitra' was conceived and completed by junior E&TC students Gandhar Tannu, Kunjan Taori and Sachin Patil in 2011.Total Duration of this project was 3 months. This project was selected for the finals of 'Techno Champ' - a national level innovation competition organized by 'John Deere'.

9. GSM MODEM
• Accepts a SIM card and operates over a subscription to a
mobile operator.
• For mobile operators GSM modem and mobile ‘feel’ the same.
• Allows COMPUTER to communicate over the mobile network.
• Exposes an interface that allows APPLICATIONS (eg. NowSMS)
TO SEND AND RECEIVE MESSAGES.
• For the purpose GSM modem must support an “EXTENDED AT
COMMAND SET” as defined in the ETSI GSM 07.05 and 3GPP
TS 27.005 specifications.
• Quick and efficient way to get started with SMS, because a
SPECIAL SUBSCRIPTION TO AN SMS SERVICE PROVIDER IS NOT
REQUIRED
• Sender is pays for the message delivery, hence in some parts of
the world GSM modem act as COST EFFECTIVE SOLUTION FOR
RECEIVING MESSAGES.

10. 8051 based MICROCONTROLLER
FEATURES:
RAM – 128 Bytes (Data memory)
ROM – 4Kbytes (ROM signify the on – chip program space)
Serial Port – Using UART makes it simpler to interface for serial communication.
Two 16 bit Timer/ Counter
Input/output Pins – 4 Ports of 8 bits each on a single chip.
Interrupt Sources
8 – bit ALU (Arithmetic Logic Unit)
Harvard Memory Architecture – It has 16 bit Address bus (each of RAM and ROM) and 8
bit Data Bus.
8051 can execute 1 million one-cycle instructions per second with a clock frequency of
12MHz.
WHY 8051:
Ease-of-use
Market availability
Less power usage
Smaller processing power
More integrated features like RF and USB
Smaller form factors

11. 16×2 LCD DISPLAY
Intelligent, with built-in HITACHI HD44780 compatible
LCD controller and RAM providing simple interfacing
61 x 15.8 mm viewing area
5 x 7 dot matrix format for 2.96 x 5.56 mm characters,
plus cursor line
Can display 224 different symbols
Low power consumption (1 ma typical)
Powerful command set and user-produced characters
TTL and CMOS compatible
Connector for standard 0.1-pitch pin headers
