Abstract

Hydro0x01 is an open-source Internet of Things (IoT) project. Secure, production-grade IoT hydroponic automation system with ESP32, MQTT telemetry, and real-time dashboard. Production-Grade Open Source IoT Hydroponic Control System. It is built using TypeScript, Arduino, ESP32. Key capabilities include: Real-Time Environment Monitoring: High-precision tracking of pH, EC, water level, temperature, and humidity; Automated Actuator Control: Smart relays for dosing pumps, main circulation, grow lights, and ventilation; Secure Architecture: Async MQTT with TLS, offline robust modes, and RSA-2048 Signed OTA updates. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Production-Grade Open Source IoT Hydroponic Control System

2. Objective

Secure, production-grade IoT hydroponic automation system with ESP32, MQTT telemetry, and real-time dashboard

This project demonstrates how TypeScript, Arduino, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

  • Real-Time Environment Monitoring: High-precision tracking of pH, EC, water level, temperature, and humidity.
  • Automated Actuator Control: Smart relays for dosing pumps, main circulation, grow lights, and ventilation.
  • Secure Architecture: Async MQTT with TLS, offline robust modes, and RSA-2048 Signed OTA updates.
  • Edge-First Local Dashboard: Lightning fast React SPA communicating over real-time WebSockets to a Fastify backend.
  • Enterprise Data Management: PostgreSQL for persistent config state and InfluxDB for time-series telemetry.

4. Technology Stack

TypeScriptArduinoESP32

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Node.js (LTS) and npm / yarn / pnpm
  • VS Code or any code editor
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/40rbidd3n/Hydro0x01.git
cd Hydro0x01
git clone https://github.com/40rbidd3n/Hydro0x01.git
cd HydroponicOne
cd backend
npm install
cp .env.example .env
# Edit .env with your DB credentials and a secure JWT Secret
npx prisma db push
npm run dev
cd ../frontend
npm install
cp .env.example .env
npm run dev
cd ../firmware

# IMPORTANT: Clone the configuration template before compiling
cp include/config.example.h include/config.h
# Edit include/config.h with your network and MQTT details

# Edit platformio.ini to choose your hardware environment (e.g., env:esp32_dht_bmp)
pio run -t upload

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?
