Greenhouse Fertigation & Climate Control System
Modern greenhouse production requires accurate irrigation, stable fertigation, and reliable climate management.
The PKYDrip system integrates irrigation control, fertilizer dosing, sensor monitoring, and climate automation into one unified platform.
This solution is designed for medium and large greenhouses using soilless cultivation systems.

Dripper Calculation
Calculation details ignored
Total irrigation flow ≈ 30 m³/h This determines the required pump capacity and irrigation scheduling strategy.
4 Fertigation System
The fertigation system uses an open tank mixing method.
Fertilizers are mixed in a tank before entering the irrigation pipeline.
Fertilizer Tanks
| Item | Value |
|---|---|
| Quantity | 4 tanks |
| Capacity | 1000 L each |
| Channels | A / B / C / D fertilizer |
Dosing Channels
| Channel | Flow Rate |
|---|---|
| Fertilizer A | 400 L/h |
| Fertilizer B | 400 L/h |
| Fertilizer C | 400 L/h |
| Fertilizer D | 400 L/h |
| Acid | 150 L/h |
Each channel is equipped with
• electronic flow meters
• dosing control valves
5 EC and pH Monitoring
Precise nutrient management requires continuous monitoring.
Sensors installed:
| Sensor | Quantity |
|---|---|
| EC sensors | 3 |
| pH sensors | 2 |
Functions
• nutrient concentration monitoring
• automatic dosing adjustment
• fertigation ratio control
6 Climate Control System
The greenhouse is divided into two climate zones.
Each zone includes:
• temperature sensors
• humidity sensors
A weather station provides environmental reference data.
Weather Station Sensors
• wind speed
• wind direction
• solar radiation
• rainfall detection
• temperature
• humidity
7 Greenhouse Equipment Control
Each climate zone controls:
| Equipment | Function |
|---|---|
| Roof vents | ventilation control |
| Circulation fans | air circulation |
| Cooling fans | temperature reduction |
| Cooling pad pump | evaporative cooling |
| Shade screens | solar radiation control |
This enables automated climate regulation.
8 Irrigation Control System
The irrigation network includes:
| Device | Quantity |
|---|---|
| Zone valves | 4 |
| Master valve | 1 |
| Main flow sensor | 1 |
The system monitors
• irrigation flow
• fertigation ratio
• irrigation schedules
9 Remote Monitoring
The PKYDrip platform enables remote access via:
• smartphone
• laptop
• local control panel
Functions include
• irrigation scheduling
• fertigation management
• climate monitoring
• alarm notification
• historical data logging
10 System Architecture
The greenhouse system integrates four major subsystems:
1️⃣ Irrigation system
2️⃣ Fertigation system
3️⃣ Climate control system
4️⃣ Monitoring platform
All modules are connected through the PKYDrip control platform.
