Background

Maintaining the correct temperature throughout the entire supply chain—from the point of origin to the final destination—is critical for products that require precise storage conditions. Cold chain logistics is a specialized system equipped with advanced facilities and equipment to ensure that perishable items, such as fresh agricultural produce, seafood, vaccines, and precision medical instruments, are kept within their required temperature ranges during processing, transportation, and storage.

WLINK Solution

WLINK leverages advanced IoT technology to deliver an effective solution for cold chain monitoring. The industrial-grade WL-RT600 4G/3G RTU is designed to operate in harsh environments, with an operating temperature range from -40°C to +70°C, making it ideal for cold chain applications. Key features of the solution include:

• Comprehensive Sensor Integration:
  Equipped with RS-232 and RS-485 serial ports, along with AI (Analog Input) and DI (Digital Input) ports, the WL-RT600 can interface with various temperature and humidity sensors. It continuously transmits real-time      environmental data to a centralized data center over a reliable 4G/3G network.

• Threshold-Based Alarms:
  The device supports customizable temperature and humidity threshold alarms. If conditions deviate from the preset range, the M2M management platform receives an immediate alert, enabling staff to take corrective      action and maintain optimal conditions.

• Built-In GPS Tracking:
  Integrated GPS functionality allows for real-time tracking of cold chain vehicles, ensuring they remain on their scheduled routes and that goods are delivered on time.
