Rain Sensor
Irrigation inhibit and automated weather response
The Farmnet Rain Sensor detects precipitation and sends an immediate inhibit signal to irrigation and climate controllers — preventing unnecessary irrigation cycles during rainfall and triggering ventilation responses to protect crops. Integrates directly with iSMART irrigation and HOSMART climate systems.
our core strengths
Proven at Scale, Built for Performance
Farmnet manages the variables that determine crop consistency and operational efficiency. Systems are deployed across greenhouse, open-field, and indoor production environments, providing real-time control of temperature, humidity, CO₂, water delivery, and nutrient dosing.
Operating at national scale within the world's largest agricultural economy. Farmnet systems support dense networks of greenhouse and open-field operations across the highest-intensity production regions.
End-to-end production capability. Controllers, fertigation units, and system components are designed, produced, and validated within Farmnet's dedicated industrial facilities.
More than a decade of continuous development in agricultural control systems, refined through multiple technology generations and operational requirements.
Multidisciplinary engineering organisation focused on agricultural automation, control architecture, hardware design, and software systems.
Systems operating across diverse climates and production models—from arid environments to advanced controlled-environment agriculture.
Thousands of systems in continuous 24/7 operation, generating long-term performance data that informs system reliability and design.

Key Features
Irrigation inhibit
When rain is detected, the sensor triggers an automatic inhibit signal to iSMART — active irrigation programs are paused and pending starts are skipped until the rain event ends.
Climate controller integration
HOSMART can respond to rain signals by closing roof vents or adjusting shading positions to protect crops from excessive moisture or wind.
Reduced water and fertiliser waste
Eliminating irrigation during rainfall events prevents leaching, waterlogging, and unnecessary fertiliser loss in open-field and greenhouse operations.

Works Together With
Irrigation Controllers
Direct inhibit signal input to iSMART for automatic irrigation cancellation during rainfall.
