Temp / RH / Radiation Sensor
Multi-zone climate monitoring and VPD calculation
The Farmnet Temp/RH/Radiation sensor measures air temperature, relative humidity, and solar radiation simultaneously. It feeds data directly into HOSMART and HOSMART-LINK climate controllers for VPD calculation, ventilation triggers, and radiation-based irrigation and shading automation.
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
VPD calculation input
Temperature and humidity readings are used by HOSMART to compute vapour pressure deficit in real time, enabling VPD-triggered ventilation and irrigation responses.
Radiation-based automation
Solar radiation data drives radiation accumulation triggers for irrigation start via iSMART and shading automation via HOSMART.
Multi-zone monitoring
Multiple sensors can be deployed across zones, giving the climate controller differentiated data per growing area.
