PAR Sensor
Photosynthetically Active Radiation for lighting control and DLI tracking
The Farmnet PAR sensor measures light in the 400–700 nm wavelength range — the spectrum directly used by plants for photosynthesis. It drives supplemental lighting control, tracks daily light integral (DLI), and supports crop research and scheduling decisions in greenhouse and indoor farming.
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
Supplemental lighting control
PAR data drives supplemental lighting activation and dimming — lights only run when natural light falls below the crop threshold.
Daily Light Integral tracking
DLI accumulation monitoring ensures crops receive the target light dose each day — triggering lighting extension when natural radiation is insufficient.
Research and trial support
Accurate PPFD data for variety trials, light response experiments, and crop scheduling decisions in research greenhouses.
Ecosystem
