IoT Smart Parking Network
IoT infrastructure tracking parking slot availability using Arduino-powered hardware sensors communicating with a central cloud dashboard.
Decentralized City Management
Urban centers lose millions of hours searching for parking. We deployed a highly resilient IoT mesh network covering 5 acres of parking zones.
Infrared Proximity
Highly accurate obstacle detection without privacy-invasive cameras.
Wireless Mesh
ESP32 nodes pass messages to each other, removing the need for 4G on every node.
Live Map App
User-facing mobile application viewing slot states dynamically.
Technical Strategy
Hardware scaling is difficult. The protocol needed to be fault-tolerant and extremely low-bandwidth.
MQTT Message Broker
Replaced heavy HTTP protocols with lightweight MQTT utilizing Mosquitto brokers for instant pub/sub telemetry.
C++ Interrupt Logic
Arduino code relies purely on hardware interrupts rather than continuous polling, saving 90% of electricity.
WebSockets Dashboard
Built the administrative React interface using Socket.io to change the visual state of the parking space instantly.
