5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. Low cost
Communicate long distances
Easily diagnosis the surrounding environment.

12. Agricultural fields.
Agriculture research stations.
Cultivations.
Nursery plants.
