PKY-IC03 vs LoRa Solar Valve Controller (PKY-IC05): What’s the Difference?

This guide explains the key differences between PKY-IC03 and PKY-IC05, helping users choose the right wireless valve control device for their irrigation project based on power supply, functionality, and deployment scenarios.

Introduction

PKY-IC03 and PKY-IC05 are both wireless field devices used in PKYDrip irrigation systems.
However, they are designed for different purposes and different deployment conditions.

This guide explains:

  • What each device is designed to do
  • How their roles differ in an irrigation system
  • Which one should be selected for typical project scenarios

Core Design Difference

The fundamental difference between the two products is design intention.

  • PKY-IC03 is a wireless execution controller designed for flexibility.
  • PKY-IC05 (LoRa Solar Valve Controller) is a dedicated solar-powered valve actuator designed for simplicity and ultra-low power operation.

They are not interchangeable, and neither one is an upgrade of the other.

When to Use PKY-IC03

Choose PKY-IC03 when:

  • Field power supply is available or larger batteries can be used
  • Additional field sensors are required
    • Pipeline pressure sensor
    • Soil moisture sensor
    • Other monitoring devices
  • Valve operation depends on local feedback or conditions
  • The project is engineered and supervised by technical staff

Typical examples:

  • Greenhouses with pressure monitoring
  • Main or sub-main pipeline zones
  • Mixed systems requiring feedback before valve operation

When to Use PKY-IC05

Choose PKY-IC05 (LoRa Solar Valve Controller) when:

  • The site has no electricity
  • Only valve open/close control is required
  • Long-term unattended operation is expected
  • Fast installation and low maintenance are priorities

Typical examples:

  • Orchards and vineyards with distributed zones
  • Open-field agriculture with long distances
  • Projects where trenching cables is impractical

System Architecture Perspective

In a modular PKYDrip system, both devices may coexist:

  • PKY-IC03 handles zones requiring sensors or flexible control
  • PKY-IC05 handles simple valve-only zones powered by solar energy

This separation improves system reliability and reduces unnecessary complexity.



Summary

  • PKY-IC03 is a flexible wireless execution controller suitable for sensor-integrated zones
  • PKY-IC05 is a dedicated solar-powered valve controller optimized for simple, reliable valve control
  • Selection depends on power availability, functional requirements, and maintenance expectations

If you are unsure which device fits your project, reviewing field conditions and control requirements is the best starting point.
