Abstract:

This project presents an integrated smart city system utilizing Arduino controllers to enhance urban infrastructure through automation.

The system features a line follower robot with an MQ3 alcohol sensor to detect and prevent alcohol consumption in drivers.

It includes a smart parking management subsystem with IR sensors and an LCD display to monitor and display parking slot availability, while a motor driver manages gate operations.

Automatic street lighting is controlled by IR sensors to optimize energy use based on movement detection.

Fire safety is addressed with a smoke sensor and alert buzzer, while a smart water supply system uses a moisture sensor and relay-controlled pump to manage water levels.

Additionally, home automation is achieved with IR sensors that activate lights upon detecting occupancy.

This approach highlights the effective integration of various smart technologies to improve safety, efficiency, and resource management in urban environments.

• Enhance road safety through alcohol detection.
• Optimize parking management with slot monitoring and automated gate control.
• Improve street lighting efficiency with presence detection.
• Enhance fire safety with smoke detection and alerts.
• Manage water supply effectively with level monitoring and automated pumping.
• Automate home lighting based on occupancy detection.
