3. INTRODUCTION
 primary occupation
 Obstruction in agriculture due to migration.
 use of wireless sensor networks for monitoring.
 Various sensor are deployed at different locations in the farm.
 Our product focuses on developing devices and tools to manage, display
and alert the users.

4. EXISTING SYSTEM
 The existing method is one of the oldest ways in agriculture.
 In this method farmers they themselves verify all the parameters for
cultivation.
 farmers only through their experience monitor the cultivation process.
 Some farmers mostly grow single crop which is monsoon dependent.

5. DISADVANTAGES OF EXISTING
SYSTEM
 Lack of monitoring and improper farming method.
 Use of excess fertilizers.
 Agricultural field isn’t continuously monitored

6. PROPOSED SYSTEM
 various sensors are deployed in different parts of the field.
 Data is transmitted to the microcontroller.
 Data is verified with the threshold values.
 This alarm is sent as a message to the farmer.

Voltage = Voltage / 10;
Disp_Line1[11] = (Voltage%10)+48;

ALCD_Message( 0x01, "");
ALCD_Message( 0x80, "temp is high");
MSDelay(500);
GSM_Send_SMS( Mb_Num, "temp is
high");
}

15.  A pH sensor is a scientific instrument that measures the
hydrogen-ion activity in water-based solutions , indicating
its acidity or alkalinity expressed as pH .The pH meter measures
the difference in electrical potential between pH electrode and
reference electrode therefore is sometimes referred to as a
“ potentiometric pH meter“ .

22. BUZZER
 A buzzer or beeper is an audio signalling device, which may
be mechanical, electromechanical, or piezoelectric (piezo for
short).
 Based on the output of the PIR sensor.
 Used as an alarm for the intruder detection.
