Long Range Li-Fi Data Transfer Module – Wireless Visible Light Communication

The Long Range Li-Fi Data Transfer Module is an innovative Visible Light Communication (VLC) system that enables wireless data transmission through LED illumination. By modulating light waves at high frequencies, this module provides a secure, high-speed alternative to traditional Radio Frequency (RF) communication. It is an ideal solution for environments where WiFi or Bluetooth may cause interference or pose security risks.

High-Security Optical Communication

Li-Fi technology offers intrinsic security, as data is confined to the area illuminated by the light source, preventing “bleeding” through walls—a common vulnerability in RF systems. This specific long-range module is optimized for consistent performance over distances of 8 to 10 feet in clear-path environments. The receiver features an onboard variable resistor (Trim Pot), allowing users to manually calibrate the sensitivity and maximize the effective data transfer distance based on ambient lighting conditions.

Key Features

• Visible Light Communication: Uses LED light for data transmission, avoiding RF interference.

• Long Range Capability: Reliable data transfer up to 8–10 feet without obstacles.

• Tunable Sensitivity: Onboard Trim Pot for distance and ambient light adjustment.

• Intrinsic Security: Data remains within the light’s line-of-sight, preventing unauthorized remote access.

• 9600 Baud Rate: Optimized for stable long-distance serial communication.

• Multi-Environment Support: Suitable for underwater, hazardous, and medical settings.

Technical Specifications

Typical Application Scenarios

• Medical & Healthcare: Safe data transfer near sensitive MRI or surgical equipment.

• Airlines & Aviation: Providing in-flight data without interfering with cockpit electronics.

• Hazardous Environments: Reliable communication in power plants or mines where RF sparks are a risk.

• Indoor Navigation: Using ceiling lights to transmit location data to mobile robots or handheld devices.

• Underwater Exploration: Leveraging light for short-range communication where radio waves fail.

Note

Optimization Tip: To achieve the maximum 10-foot range, ensure the transmitter LED is aimed directly at the receiver sensor. If the data becomes garbled, use a small screwdriver to slowly adjust the variable resistor on the receiver side until the serial output stabilizes.
