Parallel Street Lights Automation, Monitoring
and Controlling
PROBLEM STATEMENT DEFINITION:• Automate street light based on light availability• Use Raspberry Pi as gateway• Use ESP 8266 as node• Manual and automatic powering• Should be able to monitor and control• Develop suitable web and app interface for the same
EXISTING METHOD• Conventional manual system uses physical switches which
are turned ON in the evening and OFF in the morning
• Current automated system are based on time
Disadvantages of Existing SystemManual SwitchingMore Energy ConsumptionNot effective for changing seasons
Proposed solution• Light intensity based street light • Works on Two modes
• Manual and Automatic• Can be monitor and control using web or mobile interface
Advantages of proposed solutionEnergy efficient and longer lifeChanges according to seasonsReduces manual labour and maintenanceNotifies on LED repair

Benchmarking
Current scope in Market• 315 million conventional street lights around the world • Which would grow to 400 million by 2020• US, UK and China are the leading market• In India, Andhra Pradesh and Rajasthan have the largest
requirement • Growing role in cities around the world• Market remains young
• THREATS:• OPPORTUNITITIES:
• WEAKNESS:• STRENGTHS
- Energy-efficient- Less manual
labour- Based on light
intensity
- Requires calibration - Requires
Standardizing

SWOT
Future advancements• At nights, excess speed of motorists can be indicated by proper traffic
speed sensors and reducing 5% lighting.• Solar panels and batteries can be used alternate source of energy• Fault detection alarm• Automation based on motion detection as well
