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 connected near to the field drops below the threshold level for irrigation and Field starts drying and also 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. 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 a sms from mobile phone.

4. 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.

5.  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.

6. 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 bps

9. Circuit Description & Working
• GSM- Based is shown in block diagram. It
comprises the power supply section, sensor
circuit, microcontroller, MAX232 driver, relay
driver & GSM-modem. The GSM board has a
valid SIM card with sufficient recharge amount to
make outgoing calls.
• The circuit is powered by regulated 5V DC. The
220V/AC mains is stepped down by transformer
X1 to deliver a secondary output of 12V,250mA.
The transformer output is rectified by bridge
rectifier BR1, filtered by capacitor C1 and
regulated by IC-7805. Capacitor C2 bypass ripples
from the regulated power supply . LED1 acts as
the power-‘on’ indicator.

10.  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.
