Smart Car Parking Monitor
Smart Car Parking Monitor connects an ESP8266 and HC-SR04 distance sensor to a responsive monitoring dashboard. Sensor readings flow through an Express API, while WebSockets keep the browser interface updated without manual refreshes.
Features
- ESP8266-based sensor reporting
- HC-SR04 distance measurement
- Express API for device data
- Live WebSocket dashboard updates
- Responsive monitoring interface

Challenges
- Translating noisy distance readings into stable parking-state updates.
- Keeping the dashboard synchronized with the device through intermittent network conditions.
- Presenting real-time parking information clearly on both desktop and mobile screens.
What I learned
- Connecting embedded hardware to a web application through an HTTP API.
- Using WebSockets for low-latency interface updates.
- Debugging the boundary between sensor behavior, networking, and frontend state.
