INTRODUCTION

In a Farming Field area, there is a need of proper

water supply to prevent it from drying and avoiding

the over flow condition.If the water level in a

borewell drops below the threshold level for

pumping, its pump motor may get air-locked or even

burn out due to dry running. It is inconvenient for

farmers to walk all the way to their fields at night just

to switch the pump motor ’off’. Besides, he may

never get to know the problem.

4

This problem can be solved by using this GSM-

based system that will automatically give the user a

call on his mobile phone when the water level in the

borewell drops below or rises to the threshold level

for pumping.

The user can also remotely switch on or switch

off the pump motor by sending an SMS from his

mobile phone. The system is simple, reliable,

portable and affordable.

FEATURES

Provides serial TTL interface for easy and direct

interface to microcontrollers

Power Indicator LED for easy debugging

Can be used for GSM based Voice communications,

Data/Fax, SMS,GPRS and TCP/IP stack

Can be controlled through standard AT commands

Comes with an onboard wire antenna for better

reception. Board provides an option for adding an

external antenna through an SMA connector

The SIM300 allows an adjustable serial baud rate

from 1200 to 115200 bps6

Circuit Description & Working

• GSM- Based is shown in block diagram. Itcomprises the power supply section, sensorcircuit, microcontroller, MAX232 driver, relaydriver & GSM-modem. The GSM board has avalid SIM card with sufficient recharge amount tomake outgoing calls.

• The circuit is powered by regulated 5V DC. The220V/AC mains is stepped down by transformerX1 to deliver a secondary output of 12V,250mA.The transformer output is rectified by bridgerectifier BR1, filtered by capacitor C1 andregulated by IC-7805. Capacitor C2 bypass ripplesfrom the regulated power supply . LED1 acts asthe power-‘on’ indicator.

When water level in the borewell dips below

sensors A and B breaks. Hence a signal is

received by the microcontroller. The

microcontroller turns the running motor ‘off’ and

makes a call to the user’s cellphone through

GSM-modem to indicate that sensing is not

connected to on the relay is switched off in this

way the device is protected from damage the

status of motor level and LED2 are shown in

table1. The GSM-modem used in this project is

SIM300/V7.03.
