3. OBJECTIVES
 The main Objective of this project is to operate a
machine / motor / liquid pumps for a fixed duration.
 If a machine is to be operated for say ten minutes,
and should be switched off after the duration, this
project provides the facility of automatic switch off
after the requited time duration.

4. EQUIPMENT
 Power Supply
 Microcontroller AT 89S52
 Relay
 Cristal Oscillator
 Reset
 LCD screen
 LED Light
 Switches (4)
 Motor/Liquid Pump

5. POWER SUPPLY
230 V AC
50 Hz
Bridge rectifier 5v Regulator
5V
DC

6. MICROCONTROLLER
4.0V to 5.5V Operating Range
Features:
-Three 16-bit
Timer/Counters.
-Eight Interrupt
Sources.
-256 x 8-bit Internal
RAM.
-Full Duplex UART
Serial Channel

7. RELAY
o IT IS A ELECTRO MAGNETIC
SWITCH
o USED TO CONTROL THE
ELECTRICAL DEVICES
o COPPER CORE MAGNETIC FLUX
PLAYS MAIN ROLE HERE

8. CRISTAL OSCILLATOR
• A crystal oscillator is an electronic
oscillator circuit that uses the mechanical
resonance of a vibrating crystal of
piezoelectric material to create an
electrical signal with a precise frequency.
• This frequency is commonly used to
keep track of time, as in quartz
wristwatches, to provide a stable clock
signal for digital integrated circuits, and
to stabilize frequencies for radio
transmitters and receivers.

9. LCD DISPLAY
 The 16x2 LCD is connected to the microcontroller.
 This means 16 characters per line by 2 lines.

10. BLOCK DIAGRAM

11. SOFTWARE
 C compiler for Embedded C programming.
 AutoCAD for circuit Design
 Proteus for simulation.

12. APPLICATION
 This Project also can be used in Solar Highway
Lightening system with Auto turn On/Off Facilities.
 Home Automation System with Auto lightening.
 Washroom Light Auto On/Off.
 Automatic Time keeping System.

13. ADVANTAGE
 Energy is saved.
 Reliable and long life.
 Low maintenance costs.
 Easy to remove, transport and store.
 Non-polluting.
 No fuel costs.
 No Wastage.
 Easy to implement.
 User Friendly.

14. FUTURE SCOPE
 The proposed system can be further enhanced by
deploying a GSM model.
 The user can control the motor pump from a
remote location using his mobile phone. The user
can also get the water level indication of the
reservoir and overhead storage tank on his mobile
phone.
 Furthermore, to check the appropriateness of the
soil, the system can be fitted with sensors like;
Humidity sensor, pH sensor, Temperature sensors
etc. which can provide the user with information
about the soil conditions via an SMS on his mobile
phone.

15. CONCLUSION
 The Whole system can be run with solar energy.
 This project can decrease the man power.
 Can Make your Life more easier.
