Các dự án embedded, IoT và computer vision mình đã thực hiện — từ firmware FreeRTOS đến pipeline nhận diện thời gian thực bằng YOLOv8.

Vehicle Tracking System using IP Camera
Dec 2025 – Feb 2026
Vehicle tracking demo
  • Integrated RTSP camera stream into a Python application on Linux; built a real-time video pipeline using OpenCV
  • Applied YOLOv8 object detection to identify and track vehicles; computed and logged X/Y coordinates for downstream analysis

Smart Auto Door System — Firebase & Web-Based Remote Control
2024 – 2025
  • Designed and implemented a full-stack smart door system on ESP32 running FreeRTOS, with preemptive multitasking handling sensor input, motor control, and cloud sync concurrently
  • Architected multi-task firmware in C: dedicated FreeRTOS tasks for door logic, Firebase sync, sensor polling, and error handling — each isolated to prevent blocking
  • Integrated Firebase Realtime Database for bidirectional state sync — door status, open/close commands, and access logs mirrored between device and cloud in real time
  • Implemented domain-based web control: users access and operate the door via a custom domain URL backed by Firebase, controllable from any browser
  • Built a fault detection & mistake-checking mechanism in C: validates sensor readings, detects stuck-door states, motor faults, and connectivity drops — triggers alerts and safe fallback modes automatically
  • Supported dual-mode operation: fully automatic (PIR/proximity sensor triggers) and manual override via web UI
  • Implemented debounce logic, fail-safe open/close limits, and a watchdog timer for reliable operation during power or network outages

Air Quality Monitoring System using ESP32 & Blynk
Jun 2025 – Aug 2025
  • Collected real-time air quality data (dust, gas) using MQ-135 and GP2Y1014AU sensors; implemented multi-channel alerts: push notification, buzzer, and LED indicator
  • Designed a monitoring dashboard on Blynk Cloud for live sensor visualization
