2. • A sustainable living requires the use of sustainable energy. This involves the
use of power in such a way that it fulfills the requirements of the present
without compromising the requirements of the future.
starting from 21st
century , the society is in fear of lacking energy from
nonrenewable energy sources in a few decades of years. So the developing
cities & towns requiring huge amount of power are tending towards the
renewable energy resources.
This means that the energy source must be renewable, and must not harm
the environment or the people working under it. The most commonly used
renewable sources of energy are: biomass, water,geothermal, wind,
and solar
One among the field like Public gardens ,which increases beauty of the cities
& towns are also consuming more power for their lighting systems and other
needfuls. One of the important factor to be considered in the mantainance of
public gardens is to utilise the power in efficient way.

4. SOLAR TRACKING
• A solar tracker is a device that orients a
payload toward the sun. Payloads can
be photovoltaic panels, reflectors, lenses
or other optical devices.

5. SOLAR TRACKING SYSTEM
• Sunlight has two components, the "direct beam"
that carries about 90% of the solar energy, and the
"diffuse sunlight" that carries the remainder. As the
majority of the energy is in the direct beam,
maximizing collection requires the sun to be visible
to the panels as long as possible.
• So with the use Solar Tracking system maximum
power can be extracted from the sun light.

9. HARDWARE REQUIREMENT
• 8051/PIC Micro Controller
• Solar Panel (for prototype Around
5W)
• Relay and Driver Circuit
• LDR
• Stepper / Geared motor ( 12v)
• Battery (6V / 12V)

10. FEATURES
• Solar panel is going to track the light intensity
based on the LDR.
• Based on light intensity & time garden lamps are
going to switch on/off.
SCOPE
• project mainly aims at the automation of the
public garden to avoid wastage of resources.

11. APPLICATIONS
• This small scale project can be implemented in
any public garden with minimum cost and
resources.
• This helps in proper utilization of the available
resources and helps in avoiding wastage of
electricity.
