Water is one of the most valuable resources on Earth. For farms, landscapes, golf courses, and even residential properties, using water wisely is critical. That's where irrigation controls come into play. These smart systems help manage when and how water is delivered, improving efficiency and saving money.
In this guide, we’ll cover everything you need to know about irrigation controls — what they are, why they matter, the different types, how they work, and how to choose the right system for your needs.
What Are Irrigation Controls?
Irrigation controls are devices used to automate and regulate the watering of plants, crops, and landscapes. These systems can be as simple as a manual timer or as complex as a fully automated, weather-responsive controller.
They work by controlling:
Water flow to different zones
Timing and frequency of watering
Duration based on soil and weather data
Modern irrigation controllers help users apply water only when and where it is needed, eliminating waste.
Why Are Irrigation Controls Important?
1. Save Water
By applying water more precisely, smart irrigation systems reduce overwatering and runoff.
2. Lower Utility Costs
Less water usage means lower water bills, especially in areas with high rates.
3. Promote Healthy Plants
Proper watering schedules prevent root rot, stress, and disease.
4. Improve Efficiency
Advanced systems automatically adjust to weather and soil moisture data.
5. Environmental Benefits
Reducing excess water use helps protect local water sources and ecosystems.
Types of Irrigation Control Systems
Manual Controllers
These basic systems include timers or knobs. They require user input and offer limited automation.
Best for: Small gardens or simple lawn setups.
Programmable Timers
Digital timers allow users to schedule irrigation cycles by day and time.
Best for: Homeowners and small commercial properties.
Weather-Based Smart Controllers
Also known as ET (evapotranspiration) controllers, these use local weather data to adjust watering schedules.
Best for: Residential and commercial properties seeking water efficiency.
Soil Moisture Sensors
These monitor the moisture level in the ground and signal the system to water only when needed.
Best for: Farms and landscapes that need soil-specific watering.
Centralized and Networked Systems
Used in large-scale agriculture or municipal landscaping, these systems connect multiple controllers and sensors.
Best for: Golf courses, cities, and large agricultural operations.
How Do Smart Irrigation Controllers Work?
Smart irrigation controls combine sensors, wireless communication, and data to fine-tune watering. Here’s how:
Data Collection: Weather stations and soil sensors gather real-time information.
System Logic: The controller uses preset algorithms to determine watering needs.
Automation: Based on inputs, it adjusts watering schedules without manual input.
User Access: Many systems are connected to apps for easy monitoring and changes.
Key Features to Look for in Irrigation Controls
1. Wi-Fi or Bluetooth Connectivity
Control your system remotely via a mobile app or web dashboard.
2. Zone Control
Manage separate areas like lawns, flower beds, or crop rows with different schedules.
3. Rain or Freeze Sensors
Shuts off watering during rain or freezing conditions to prevent waste or damage.
4. Compatibility
Ensure the system works with your existing sprinklers, valves, or drip irrigation.
5. User-Friendly Interface
Touchscreen displays, intuitive apps, and easy programming make systems more usable.
Benefits of Upgrading to Smart Irrigation Controls
Up to 50% water savings
Remote access and automation
Custom watering based on plant needs
Increased property value
Enhanced sustainability and green certification potential
Common Applications of Irrigation Control Systems
Residential Landscaping
Smart sprinkler controllers optimize lawn and garden watering schedules.
Commercial Properties
Office parks, hotels, and campuses benefit from lower maintenance costs.
Agriculture
Precision irrigation helps increase crop yield and reduce waste.
Parks and Golf Courses
Maintain green spaces efficiently across large, complex areas.
Installing an Irrigation Control System
Step 1: Assessment
Evaluate site size, climate, water source, and existing irrigation setup.
Step 2: Choose a System
Select the type and brand that best meets your needs and budget.
Step 3: Installation
This may include setting up controllers, sensors, and wiring.
Step 4: Programming
Configure zones, schedules, and sensor thresholds.
Step 5: Testing
Run a test cycle to ensure proper function and coverage.
Cost of Irrigation Controls
Basic timers: $25 – $100
Smart controllers: $100 – $300
Soil sensors: $50 – $200 each
Professional installation: $200 – $1,000+, depending on complexity
Costs vary based on brand, features, and scale.
How to Choose the Right Irrigation Controls
Ask yourself:
What size area am I irrigating?
Do I need remote access or automation?
How many zones do I need to manage?
Is my area affected by drought restrictions?
Do I need soil or weather sensors?
Look for systems with good customer reviews, manufacturer support, and clear setup guides.

FAQ: Irrigation Controls
What is an irrigation controller?
A device that automates when and how water is applied to landscapes, lawns, or crops.
Are smart irrigation systems worth it?
Yes, they save water, reduce costs, and improve landscape health.
Can I install irrigation controls myself?
Many systems are DIY-friendly, but large setups may need a pro.
How many zones can I control?
Most systems range from 4 to 16 zones. Commercial systems may offer more.
What are water restrictions?
Local rules limiting water use during droughts. Smart controls help you comply.
How often should I water?
It depends on weather, soil, and plant type. Smart systems adjust automatically.
Do smart controllers need Wi-Fi?
Many do for full features, but some work offline with basic functions.
What’s the lifespan of a controller?
Most last 5–10 years with proper care and updates.
