What is hydro0x01?

HydroponicOne is an open-source system for automating and monitoring hydroponic gardens, the kind where plants grow in water rather than soil. The gap it fills is between cheap hobbyist setups and expensive industrial equipment: it gives you professional-grade automation without the enterprise price tag. The system works in two parts. A small microcontroller board (an ESP32) sits in your growing environment, reading sensors for water pH, electrical conductivity, water level, temperature, and humidity. It then sends all that data wirelessly over a secure messaging protocol to a backend server running on your local network. That server stores the data in two databases, one for settings and configuration, the other for historical sensor readings over time. A web dashboard lets you view everything in real time and control pumps, lights, and ventilation fans automatically based on the sensor readings. You would use this if you run a hydroponic setup, from a home herb garden to a small commercial grow, and want the system to automatically dose nutrients, switch lights on a schedule, and alert you when something is off, all without manually checking readings or buying proprietary automation hardware. The whole project is open-source, self-hosted on your own hardware, and documented with wiring diagrams and calibration guides.
