Smart Greenhouse Automation: An Integrated Guide for Climate, Irrigation, and Fertigation
Modern greenhouse cultivation means setting up an ideal factory for plants. However, the efficiency of this “factory” depends on the precise balance of dozens of variables such as temperature, humidity, CO₂, water, and nutrients. Establishing this balance with traditional methods means both a massive workload and high energy and water costs. However, digital agricultural technologies are turning these challenges into an opportunity.
As Esular, we transform your greenhouse into an integrated ecosystem that talks to each other, makes data-driven decisions, and operates fully automatically. In this guide, we will examine in detail the Climate Control, Smart Irrigation, and Smart Fertigation (Fertilization) systems, which are the main pillars of smart greenhouse automation, and how these systems work together.
Why is Greenhouse Automation a Necessity?
The main problems encountered in traditional greenhouse management are the biggest obstacles to productivity:
- Climate Instability: Manual ventilation leads to sudden changes in temperature and humidity. This situation creates plant stress and forms the ideal environment for the spread of fungal diseases, especially fungi and mold.
- Resource Waste: Time-based irrigation causes water and energy waste regardless of the soil's actual needs. Unnecessarily operating heating and fan systems increase energy costs by up to 40%.
- High Labor Cost: Continuous manual control of windows, valves, and fans necessitates having personnel on-site 24/7. This significantly raises operational costs.
Esular Smart Greenhouse Ecosystem: 4-in-1 Solution
Successful greenhouse automation is possible when the parts work in perfect harmony with each other. The Esular ecosystem builds this integration on 4 main components:
- Smart Climate Control: (Window, Fan, Humidity, CO₂, Temperature, Fogging, Heating)
- Smart Irrigation: (Wireless Soil Moisture Sensors and Valve Control)
- Smart Fertigation: (pH, EC, and Automatic Fertilizer Dosing)
- Sensor Network (IoT): (Wireless LoRaWAN sensors that feed the entire system)
1. Smart Climate Control: The Perfect Growth Environment
Climate control is the steering wheel of greenhouse automation. It prevents the plant from entering stress and maximizes photosynthesis efficiency.
Temperature, Humidity, and CO₂: The Key to a Homogeneous Environment
Temperature and humidity levels inside the greenhouse have a direct impact on plant health and disease risk. Additionally, the CO₂ level is of critical importance for photosynthesis (i.e., the plant's "breathing"). Esular's wireless sensors with NDIR technology measure these three parameters instantaneously.
Automatic Ventilation: Windows and Circulation Fans
The most important pillar of climate management is ventilation. The Esular system manages windows and fans with an integrated scenario:
- Automatic Window Control: The system automatically opens the windows when internal temperature/humidity rises or CO₂ drops. If wind or rain data comes from the external weather station, it automatically closes the windows to protect the plants.
- Circulation Fan Control: Fans eliminate dead air pockets inside the greenhouse. Working especially according to the data coming from the humidity sensor, they prevent condensation (dewing) on the leaf surface and reduce the risk of fungal diseases by up to 70%.
2. Smart Irrigation: Irrigate by Listening to Your Plant
The most common mistake in greenhouse irrigation is irrigating according to a schedule, not according to the soil's needs. This situation leads to water waste and root diseases.
Soil Moisture Sensors: Explore the Root Zone
Esular's wireless soil moisture sensors measure the moisture level at different depths of the soil such as 30, 60, 90 cm. In this way, you know the moisture status of not only the surface but also the actual zone where the plant root is located. The system automatically opens the valves when soil moisture falls below the "Irrigation Point" you have determined.
Pot & Substrate (Soilless Agriculture) Solutions
In soilless agriculture (cocopeat, rockwool, etc.), moisture and nutrient management is even more sensitive. Esular's special substrate sensors optimize drainage and prevent root rot by instantaneously measuring moisture and EC inside the pot.
Wireless Valve Control (Smart Valve)
Esular Wireless Valve Control Units (Smart Valve) fulfill the "irrigate" command coming from the soil moisture sensor. These devices, which are completely solar-powered and battery-operated, allow you to wirelessly manage even the most remote valve in your greenhouse thanks to a LoRaWAN range of up to 10 km.https://store.esular.com/kablosuz-akilli-vana-kontrol-unitesi-selenoid-vana-uyumlu-0
3. Smart Fertigation: Precise Plant Nutrition
Greenhouse productivity is as much about the right nutrients as it is about the right water. Smart fertigation (fertilization) is automatically giving the plant the exact nutrient recipe it needs.
Step 1: pH and EC Control (Water Quality)
For the plant to take up nutrients, it is essential that the pH and EC (nutrient concentration) values of the water are in the ideal range. Esular's wireless pH/EC sensors monitor your main water line instantaneously and determine if the water is ready for fertilization. Incorrect pH prevents the plant from taking up nutrients (nutrient lockout).
Step 2: Smart Agro (Automatic Dosing)
After the water quality is confirmed, the Smart Agro Automatic Fertilization System comes into play. By dosing with milliliter precision from A-B-C-D fertilizer tanks according to pH/EC data, it prepares the nutrient recipe specific to your plant's needs for that day and injects it into the irrigation system. This process provides up to 25% fertilizer savings.
4. Technology & Platform: Reliable Infrastructure
All these systems work integrated with each other thanks to Esular's wireless (LoRaWAN) technology and powerful cloud platform.
Smart Scenario Engine: Your Greenhouse Thinks for You
The heart of our platform is the smart scenario engine. You enable your greenhouse to make its own decisions with the "IF... THEN..." logic:
- IF Humidity > 85% THEN Open Window & Run Fan.
- IF Soil Moisture < 30% AND No Rain Expected THEN Irrigate Valve 1 for 45min.
- IF Temperature < 3°C THEN Turn on Heating & Send SMS (Frost Warning).
Conclusion: Proven Gains in Numbers
Esular's integrated automation system is not a cost, but an investment that pays for itself quickly. According to our actual field data:
- 40% Energy Savings: Optimized fan, heating, and pump operation.
- 60% Water Savings: Irrigation only when needed, in the right amount.
- 40% Yield Increase: Plants growing in ideal climate and nutrient conditions.
- 60% Labor Savings: Elimination of the need for manual control.
- Reduction in Disease Risk: Up to 70% decrease in fungal diseases thanks to controlled humidity.
In conclusion, Esular smart greenhouse automation transforms your greenhouse into a more profitable, more efficient, and more sustainable business. To step into the greenhouse cultivation of the future today and benefit from our free exploration service, contact us.
