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.
