Arduino controlled hydrophonic system

Introduction

Grow strawberries, strawberry

IoT Home growing system

Hydrophonics

Two irrigation categories

1. Sub-irrigation systems: nutrient solution is supplied from below and roots absorb moisture upward
2. Top-irrigation systems: nutrient solution is applied from above through drip emitters or sprayers

• Static solution
• Continuous-flow solution
  • NFT (nutrient film technique)
• Ebb and flow (flood and drain)

Substrates

• Rock wool
• Expanded clay aggregate
• Coconut coir
• Growstones
• Perlite / Vermiculite
• Wood fiber

Aerophonics

Aquaphonics

• combines aquaculture with hydrophonics

Theory

The following is a short version of https://www.instructables.com/Arduino-Controlled-Smart-Hydroponic-Modular-System/ by Innovart Studio.

ESP32 instead of arduino: Easier to upload data into a web server.

Structure

• PVC pipes (100 mm, 40mm), connectors,
• Tank in which the water of the system falls

Parameters:

• Air temperature and humidity
• Water temperature
• pH
• Conductivity
• Time

Actuators

• Water pump
• Growing light
• Nutrient feeder
