GSM-Global System for Mobile Communications

A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem.

GSM is the acronym for Global System for Mobile Communication.

GSM transmits data using radio waves.

To communicate with GSM modem, AT commands are required.

Microcontroller sends these commands to the GSM modem, which is then activated to perform the required operation.

The MAX 232 is an IC.

converts signals from an RS-232 serial port to signals suitable for use in TTL compatible digital logic circuits.

The MAX232 is a dual driver/receiver and typically converts the RX, TX, CTS and RTS signals.

MAX 232 acts as a station between the GSM modem and the micro controller.

A water pump is any device for moving water.exists in an enormous variety of styles.Some uses of water pumps include:

1. Obtaining water from ground wells for drinking, cooking, and other purposes.

2. Moving water in active solar heating systems.

The µVision KEIL combines project management & makes :

i. source code editing,

ii. program debugging,

iii. complete simulation.

The µVision development platform is easy-to-use.

Help’s you to quickly create embedded programs that work.

The µVision editor and debugger are integrated in a single application.

This project gives information about off-grid irrigation system.The farmer (user) can water the fields from any place. This project uses linear programming. Using this system, one can save

manpower, as well as water to improve productivity.

Low cost Communicate long distances Easily diagnosis the surrounding environment.

Agricultural fields.

Agriculture research stations.

Cultivations.
