ParkSmart: IoT-Based Car Parking Management System Using Blynk

ParkSmart is a smart IoT-based car parking system designed to efficiently monitor and manage parking slots using real-time data. The system is built using NodeMCU (ESP8266) or ESP32, integrated with ultrasonic sensors or IR sensors to detect vehicle presence in each parking slot. The availability of parking spaces is updated live and displayed on the Blynk mobile application, allowing users to remotely check slot availability before arrival.

When a vehicle occupies or leaves a slot, the system updates the status on the Blynk dashboard instantly. LED indicators at each slot (e.g., green for vacant, red for occupied) provide on-site visual feedback. The system can also be enhanced with features like gate control via Blynk, SMS alerts, or LCD display for local monitoring.

Ideal for malls, office spaces, apartments, and public parking areas, ParkSmart demonstrates how IoT and cloud-based platforms like Blynk can transform urban mobility and smart city infrastructure.
