Abstract
The rapid growth of urban populations has intensified parking congestion in metropolitan areas, leading to excessive fuel consumption, traffic delays, and environmental concerns. This paper presents the design and implementation of an Internet of Things (IoT)-based smart car parking system using Arduino Uno, NodeMCU (ESP8266), and infrared (IR) sensors. The proposed system detects vacant parking spaces and communicates availability to drivers through the Blynk IoT platform in real time. The system was designed, simulated, and tested using integrated hardware and software components, with results showing reliable detection and efficient data transmission to the user interface. The project demonstrates a scalable, cost-effective solution suitable for commercial and residential applications.
