DeepCultureMonitor

A Raspberry Pi-based monitoring and control system for deep water culture (DWC) hydroponics.

Supports pH, EC, temperature, and water level monitoring as well as adjustments via solenoid and pump control.

Currently supports up to six peristaltic pumps. These can be used, for example, for pH Up, pH Down, and four nutrient or additive solutions.

Modules

This project comprises three modules, each implemented within its own Docker container:

Devices Found in build/ and src/ and launched via start_budbucket_devices.sh. Uses a state machine pattern to read data from sensors and write it to a SQLite database in a loop.
Server Found in server-build/ and server-src/ and launched via start_budbucket_server.sh. Runs a very simple Flask server that reads sensor data from the SQLite database and populates zoomable charts created using Chart.js.

Documentation of hardware configuration
Orchestration via docker-compose
Light level monitoring (on/off, and then lux measurement)
Support max/min limits for water level, pH, and EC with automated fertigation/water level adjustments
Control using P(I)D control
Full grow lifecycle automation
Configurable alerts via email and/or SMS
