LoRa Off-Grid Irrigation System

A modular LoRa-based irrigation solution designed for remote farms without electricity or 4G coverage. The system enables reliable valve and pump control with verifiable operation using flow and pressure feedback.

What Problem Does This Solution Solve?

Many irrigation projects face the same challenges:

  • Water sources are far from the farm or control room
  • No stable electricity supply at field level
  • 4G or WiFi coverage is unavailable or unreliable
  • Manual pump and valve operation wastes time and labor
  • Pump status cannot be verified remotely

The LoRa Off-Grid Irrigation System is designed specifically for these conditions.

Solution Overview

This solution uses LoRa long-range communication to connect remote field devices without relying on public networks.

It enables:

  • Remote valve and pump control
  • Solar-powered, unattended operation
  • Verification of pump operation using flow feedback
  • Measurable and stable irrigation control

The system follows a modular design:

Start simple. Upgrade anytime.

  • PKY-EG08 – LoRa Gateway
    Acts as the communication hub for the LoRa network.

  • PKY-IC05 – LoRa Solar Valve Controller
    Solar-powered valve control for irrigation zones without electricity.

  • PKY-IC06-PUMP – LoRa Solar Pump Controller
    Remote pump start/stop with operation verification via flow sensor.

  • PKY-DAT01 – Data Acquisition Terminal (Optional)
    Collects and reports flow, pressure, soil moisture, weather, and water-level data at configurable intervals.

Each module can be deployed independently and expanded as the project grows.

How the System Works

  1. The LoRa gateway establishes a long-range communication network.
  2. Valve and pump controllers receive control commands via LoRa.
  3. Pumps and valves operate using solar power.
  4. Flow and pressure data confirm real pump operation.
  5. Sensor data is reported periodically for monitoring and automation.

Control is not only remote — it is verifiable and measurable.

Typical Deployment Scenarios

  • Remote wells and reservoirs
  • Off-grid orchards and vineyards
  • Large open-field farms
  • Solar-powered irrigation projects
  • Areas where trenching cables is impractical

Why Verification Matters

Traditional remote switching only sends commands.

This solution adds feedback:

  • Flow sensors confirm water output
  • Pressure data supports safety checks
  • Operators know whether the system is actually running

This reduces uncertainty and improves long-term system stability.

Information Needed for System Design

To prepare a tailored solution, we typically ask:

  • Distance between water source and fields
  • Pump type and power (solar or AC)
  • Number of irrigation zones
  • Required flow rate and pressure
  • Whether flow or pressure monitoring is needed

This ensures correct module selection and reliable operation.

Design Note: Pump Operation Verification

In remote and off-grid irrigation systems, starting a pump remotely is not enough. It is critical to confirm that water is actually being delivered.

By adding a flow sensor at the pump outlet, the system can verify real pump operation and detect abnormal conditions early.
