1. Gsm Modems Based Irrigation Water Pump Controller for Illiterates

2. Aim:
Designing an embedded system which can completely help a former to supply water to the crops by sending messages in Irrigation field.
Objective
This project deals with irrigation application.
Physical effort and inconvenience
Loss/ Frequent damage of irrigation equipment
Wastage of water and electricity

3. EMBEDDED SYSTEMS Introduction
An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions.
An embedded system is some combination of computer hardware and software, either fixed in capability or programmable.

9. GSM MODEM Block Diagram of GSM Connection diagram
The GSM modem being a serial communication device is connected to the serial port or a serial device through a serial connector. The power input to the modem is given through a 9v ac adapter

10. DESCRIPTION
GSM stands for Global System for Mobile Communication. It is a globally accepted standard for digital cellular communication.
GSM is the name of a standardization group established in 1982 to create a common European mobile telephone standard that would formulate specifications for a pan-European mobile cellular radio system operating at 900 MHz
The GSM modem basically consists of a
SIM card holder to hold the activated SIM card for sending and receiving SMS.
5V AC power supply header to which the 5v ac adapter is connected.
Power led which gives the indication of modem status that is on or off.
9 pin female to which the GSM antenna is connected.

11. RELAY Relay showing coil and switch contacts
Circuit symbol for a relay
Relay showing coil and switch contacts
A relay is an electrical switch that opens and closes under the control of another electronic circuit. In the original form, the switch is operated by an electro magnet to open or close one or many sets of contacts

12. Applications: Electronics applications and consumer devices
Industrial automation and process control software.
Home appliances
Security alerts

13. CONNECTION DIAGRAM
This is how we connect Gsm Modems Based Irrigation Water Pump Controller for Illiterates to the motor

14. ADVANTAGES DIS-ADVANTAGES Low power consumption Global range
Easy to operate
Flexible to run at specific intervals
DIS-ADVANTAGES
Communication delays
Not work in remote areas
Undetectable internal problems in motor

15. Conclusion
The project “Gsm Modems Based Irrigation Water Pump Controller for Illiterates.” has been successfully designed and tested.
Secondly, using highly advanced IC’s and with the help of growing technology the project has been successfully implemented.
It took great change and flexible to the farmer while power cuts
