final ppt. of my project.

1. ENERGY SAVING STREET LIGHT TIMER GROUP-2: ABHIT SINHA POOJA CHHABRA CHARU AGRAWAL AKSHITA AGGARWAL VIKAS SINGH ANKIT DESWAL HIMANSHU BHAGWAN PARSHURAM INSTITUTE OF TECHNOLOGY 2nd YEAR

2. INTRODUCTION This project aims at saving electricity. It's a very good and an innovative idea.......to save our precious ENERGY RESOURCES. It utilizes our basic knowledge and the specific requirement of ELECTRICITY by the people of a particular place...

3. BASIC CONSTRUCTS It is basically a REAL TIME CLOCK that displays the following data :1. TIME2.DAY3.DATE4.SUNSET TIME (IF ASKED TO DISPLAY)5.SUNRISE TIME (IF ASKED TO DISPLAY) It also enables us to set MULTIPLE ALARMS. The sunset and sunrise time act as triggers for the switching of lights. It sets the light intensity required by the user at that time automatically , and hence we make judicious use of electricity(this prospect makes it an energy saving device).

4. HARDWARE CONNECTIONS ARDUINO BOARD USB CABLE COMPUTER

5. SETUP Street Light Switching ALARM OUTPUT Trigger MEMORY BLOCK DIAGRAM 1.Set lat, lon, time zone 2.Set light switching timings 3.Set alarms CALCULATE sunrise and sunset time Set lat, long , time zone MENU (Start) USER SETUP

7. Start ( )

9. Set light settings ( )

10. Set alarm ( ) Set longitude, latitude and time zone ( ) Input longitude, latitude and time zone Set light settings ( ) Set the increment, decrement time and night mode time Set alarm ( ) We can set upto 5 alarms in our digital clock.

11. Contd. Void Loop ( ) Set Sunrise and Sunset time according to the latitude, longitude and time zone if not set Digital clock display: Displays : time date day of week sunrise time(if required) sunset time (if required) It automatically changes light voltages according to the present time and the sunrise and sunset time.

12. DESIGN It is designed using Arduino mega board , a USB cable connected to a computer.

13. IMPLEMENTATION This project is just a simulation of a real life project . Here we will demonstrate it using the Arduino kit .THE REAL PROJECT IS THE ADVANCED FORM OF THIS PROJECT ONLY....i.e. a single LED in this project will be replaced by a number of street lights (to be controlled) in the real project.

14. IMPORTANCE This project is easy to use and install and has a number of advantages. All the settings are to be done by the user during the time of installation only...once installed, it requires no maintenance. It describes the best way of saving electricity without human intervention . It can also be used as a digital clock that displays time and date and has multiple alarm properties.

15. FUTURISTIC APPROACH This project can be used anywhere in the world, its database adjusts itself according to the present latitude, longitude and time zone entered by the user. It can be used to automate street lights in an housing society, hostel, park, hotel corridors and in college premises or anywhere you wish to install it.
