Utilization of LED Grow Lights for Optical Wireless Communication-Based RF-Free Smart-Farming System

Area of Science:

• Agricultural Technology
• Optical Communications
• Sustainable Farming

Background:

• Indoor smart-farming relies on artificial lighting and radio-frequency (RF) networks for monitoring.
• RF communication may negatively impact vegetable growth and health.

Purpose of the Study:

• To propose an energy-efficient, RF-free communication system for indoor smart-farming using light-emitting diodes (LEDs).
• To enhance vegetable growth by integrating communication with beneficial green light.

Main Methods:

• Utilizing visible light communication (VLC) and optical camera communication (OCC) for data transmission.
• Modulating data onto green LED grow lights for uplink and using white LEDs with photodetectors for downlink.
• Modularizing smart-farming units for flexible mobility.

Main Results:

• Demonstrated a proof-of-concept for an RF-free smart-farming communication architecture.
• Achieved maximum data rates of 840 b/s for uplink and 20 Mb/s for downlink.
• Confirmed the feasibility of using modulated green light for communication and plant growth.

Conclusions:

• The proposed LED-based communication system offers a viable, energy-efficient alternative to RF in smart-farming.
• Integrating communication with beneficial light wavelengths enhances agricultural technology.
• This approach promotes healthier plant growth and flexible, modular farming systems.
