The document outlines a smart solar street lighting system proposed by Sethu Institute of Technology aimed at enhancing street safety and energy efficiency in Chennai under the Nirbhaya scheme. It features solar power, motion sensors, weather displays, and an emergency alert system, offering community services like agricultural information and improved lighting in poorly illuminated areas. The initiative is intended to save energy, promote safety, and support local farmers, ultimately improving quality of life in village communities.

2. BACKGROUND
 For the 2022-23 year grant request, the Minister for
Municipal Administration KN Nehru announced that
more street lights would illuminate the poorly-lit
streets under the Nirbhaya scheme for the protection of
women.
 As per reports by the New Indian Express, an
additional 5,594 street lights and 85 high mast lights
will be installed at an estimated cost of 33.57 crores
₹
across Chennai.
 Currently, there are about 2,91,415 LED street lights in
the city maintained by the corporation's electricity
department.

3. PROBLEM
 The electrical energy consumption of street lighting constitutes
an important part of total energy consumption. Saving energy
in street lamps is therefore important for total energy savings.
 Poor lit streets are perceived as very dangerous for pedestrians
 Without any lighting pose is danger to women to walk for long
distance
 It may increase the risk of collisions motorised forms of
transport

4. SOLUTION
• Light poles are used to promote security in urban areas
and to increase the quality of life by artificially extending
the hours in which it is light so that activity can take place.
• Lightings also improve safety for drivers, riders, and
pedestrians.

7. PROPOSED SOLUTION
Street light is an essential for public services that provides so for environments, importantly at night times and
heavy traffics. They secure lighting can be modernized to helpful for village communities.

8. PROPOSED SOLUTION
Need of the design :
 Energy consumption is controlled by this designed solution.
No need for electricity

9. PROPOSED SOLUTION
Weather indication :
 Accurate weather data can assist farmers in determining when they should work
efficient in their precautions. By using BMPI80 & DHTII sensors.
Raining precautions for the
peoples

10. PROPOSED SOLUTION
Emergency alert :
 In case of emergency vehicles need to cross remote areas, instructed to leave way for
vehicles by using RFID technology.
Instructed to leave way

11. PROPOSED SOLUTION
Advertisement display :
 By making advertisement on display of light pole is the easy way to convey all social information's to the
people directly. Agricultural related information (regarding govt. schemes, crop details, pest control,
recent advancement in agriculture and crop etc.) will be passed then and there. So, there is need to go for
agricultural office for getting information
Smart way to convey

12. NOVELTY
 Fit and Forget device
 Excellent for remote villages
 High reliability and durability
 Perfect design
 Easy Installation
 Low maintenance

13. OUTCOMES
 Village is illuminated independently by off grid solar panel
 Farmers can able to know all the detail about agriculture from their premises
 Energy conservation so that small solar panel can be used. Or stored energy can be
used for some other purposes
 Weather display helps the villagers
 Fault detection in our system will help them to get illumination continuously
 Emergency alert system will help the villagers to save life
