Frameworks: ESP-IDF, Arduino, PlatformIO
Interfaces: LVGL, I2C, SPI, I2S, UART, SDI-12, Ethernet, WiFi, BLE
Protocols: MQTT, REST API, JSON-RPC, WebSocket, RTMP/HLS, Blynk
Languages: C, C++, Python, PHP
Other: LittleFS, FreeRTOS, HiveMQ, MySQL, Flask, FFmpeg, Nginx, Telegram Bot API
| Project | Stack | Description |
|---|---|---|
| RDWC Hydroponic Controller | ESP32 + PHP + MySQL + Telegram | Full-stack hydroponic monitoring: pH, EC, temperature, dosing pumps, web dashboard, cloud logging |
| Industrial Megaphone | ESP32-P4 + Ethernet + ES8311 | Network-controlled audio player for factories. REST API, LittleFS caching, I2S codec |
| Payme Payment Terminal | ESP32 + Flask + MQTT + Payme | IoT payment terminal for vending machines. QR generation, real-time MQTT notifications |
| Street Aroma Vending | ESP32 + LVGL + Payme + Servo | Perfume vending machine: touchscreen UI, QR payment, servo dispensing, remote price management |
| RTMP-HLS Streaming | Raspberry Pi + FFmpeg + Nginx | Live video streaming: camera → RTMP → HLS → HTML5 browser player |
| Wireless Soil Sensor Gateway | ESP32-S3 + SDI-12 + Deep Sleep | Battery-powered 4-sensor soil monitoring: moisture, temperature, EC. 1-hour cycles, ~10μA sleep |
| Bio Master | Arduino + ESP8266 + Blynk | Smart greenhouse automation: 10 crop profiles, auto irrigation/heating/lighting, captive portal WiFi setup |
