Wireless Valve Control for Open Field Irrigation | No Wiring Solution

Control irrigation valves across large farms without cables using LoRa wireless technology. Ideal for open-field irrigation, retrofit projects, and solar-powered systems.

Wireless Valve Control for Open Field Irrigation

Managing irrigation across large farms often becomes difficult due to long distances, complex wiring, and scattered irrigation zones.

This solution provides a wireless valve control system that eliminates the need for trenching and cabling, making it ideal for modern open-field irrigation projects.

The Problem

In many farms, irrigation systems face challenges such as:

  • Long distances between irrigation zones
  • High cost of cable installation
  • Difficult maintenance of buried wires
  • Limited flexibility when expanding the system

These issues become more significant as farm size increases.

The Wireless Solution

The PKYDrip wireless irrigation system uses a LoRa-based communication network to connect irrigation zones without wiring.

Instead of running cables, each irrigation zone is equipped with a wireless valve controller, and all devices are connected through a central gateway.

System Structure

A typical system includes:

1. LoRa Irrigation Gateway

  • Central communication unit
  • Sends commands to all valve controllers
  • Can connect to cloud or local controller

→ View Gateway

2. Wireless Valve Controllers

  • Installed near each irrigation zone
  • Controls solenoid valves or electric valves
  • Operates on battery or solar power

→ View Valve Controller

3. Optional Solar Power System

  • Used in remote areas without grid power
  • Supports long-term unattended operation

How It Works

  1. The gateway sends irrigation commands
  2. Wireless nodes receive signals via LoRa
  3. Each node opens or closes its valve
  4. Optional sensors provide feedback (flow/pressure)

This allows centralized control with distributed execution.

Typical Use Cases

Large Open Field Farms

  • 10–200+ acres
  • Multiple irrigation zones
  • Long-distance valve distribution

Irrigation System Upgrade

  • Existing pipelines remain unchanged
  • Add wireless control without trenching

Remote or Off-Grid Projects

  • Solar-powered pump + valve system
  • No wired infrastructure required

Key Benefits

No Trenching or Wiring

Significantly reduces installation time and cost.

Flexible Expansion

New irrigation zones can be added easily without redesigning the system.

Lower Maintenance

No cable damage or underground wiring issues.

Suitable for Solar Systems

Works well in off-grid environments.

Engineering Considerations

When designing a wireless irrigation system, several factors must be considered:

  • Signal coverage and distance
  • Power supply strategy (battery vs solar)
  • Valve type compatibility
  • Fail-safe design for communication reliability
