M.VENU GOPAL REDDY

2.  This project is aimed to design a system to
control the agriculture field motor by using
a wireless technology called GSM technology.
 This GSM Modem can accept any GSM
network operator SIM card and act just like a
mobile phone with its own unique phone
number.

3. An embedded system is:
 A micro controller /microprocessor based
system that is built to control the function of
equipment ,machinery or plant.
 Combination of hardware and software for
specific application.
Hardware:
Processer ,memories , peripherals ,power
supply etc…
Software:
Assembly language program like c,c++…

4. HARDWARE:
 Micro controller : AT89x series
 Crystal : 11.0592 MHz
 Driver IC : Max232
 GSM modem : sim300
 Driver IC : L293D
 DC motor
 Power supply
 Transformer : 12V step down
 Filter : 1000uf/25V
 Voltage Regulator : 7805, 7812

5. SOFTWARE:
 Keil IDE

8.  GSM modem is interfaced to the controller through
serial port along with a motor.
 The GSM modem performs the task of receiving the
message from the mobile and sending the messages
to the mobile from the controlling unit.
 If the farmer wishes to water his field, he needs to
switch on the motor.
 Thus, he has to send a predefined message to the
modem from his mobile. The GSM modem receives
this message and intimates the same to the
microcontroller.
 Now it is the job of the controller to switch ON/OFF
the motor in accordance with the received message.
