OFF the motor and sends SMS indicating empty well (dry running) conditions. The micro-

controller switches ON the motor again when ever water rises beyond HL level and sends sms

indicating resumption of task. Using analog voltage inputs for LL and HL levels increases the

flexibility of system by just incorporating different threshold levels in program for different soil

conditions.

In both conditions (water level sensor) protection for induction motor. However, in order

to ensure maximum reliability, one temperature sensor is mounted on body of motor, to measure

ambient temperature whenever temperature difference exceeds specified safety limit, signal is

sent to switch OFF pump along with error indication to LCD display and conveying SMS to user

cell phone to indicate probable fault occurrence. We are using soil moisture sensor placed at the

plants to know how much water content is present in the field

Generally frequent power cuts and insufficient rains at various stages of growth are one

of major causes of losses to farmers. Many farmers use induction motor pumps to irrigate their

f arms from wells. In this application, GSM modem receives any incoming SMS message is

directly routed to micro-controller and any outgoing text message is directly sent by micro-

controller to designated cell phone number without being stored in control system cell phone

memory. As a result, phone memory is not in undated with messages in spite of many messages

being transferred.

TECHNOLOGY:

GSM:

GSM (Global System for Mobile communications) is the technology that underpins most

of the world's mobile phone networks. The GSM platform is a hugely successful wireless

technology and an unprecedented story of global achievement and cooperation. GSM has

become the world's fastest growing communications technology of all time and the leading

global mobile standard, spanning 218 countries. GSM is an open, digital cellular technology used

for transmitting mobile voice and data services. GSM operates in the 900MHz and 1.8GHz bands

GSM supports data transfer speeds of up to 9.6 kbps, allowing the transmission of basic data

services such as SMS.

RESULT:

This project finds application in domestic agricultural field. In civilian

domain, this can be used to ensure faithful irrigation of farm field, since we have

the option of finding out moisture level of soil in a particular area.
