How Bluetooth Temperature Data Loggers Realize Automation in Cold Chain Logistics?
Cold chain logistics refers to the end-to-end management of temperature-sensitive products—such as food, pharmaceuticals, or chemicals - under precisely controlled environmental conditions throughout storage and transport.

Why Is Temperature Monitoring Important in Cold Chain Logistics?
During cold chain logistics, even minor temperature or humidity fluctuations can lead to spoilage, reduced product effectiveness, or regulatory non-compliance. Traditionally, monitoring systems required manual data downloads after delivery, often delaying critical responses and increasing the risk of human error. Freshliance deeply understand the urgent needs for effective methods and now provided modern solutions like Bluetooth temperature data loggers paired with 4G/WiFi gateways offer automated, real-time monitoring and cloud-based uploads, ensuring data accuracy, operational efficiency, and complete cold chain visibility.

How to Use Bluetag Bluetooth temperature data loggers and Gateway in Cold Chain Logistics?
Freshliance’s smart solution by using Bluetooth temperature monitors combined with 4G/WiFi gateways to realize automatically upload data to cloud. Here’s how it works:
During transport, the Bluetooth temperature and humidity data logger records temperature and humidity continuously, it can also as standalone monitors, allowing users to remotely get data via Bluetooth and share data among multiple users.
Once the goods arrive at the freight yards or transfer stations where a gateway is installed, the Bluetooth temperature data loggers automatically connects to the gateway. The gateway is designed to automatically collect data from all pass-by BlueTag series Bluetooth temperature data loggers.
The data is immediately uploaded to the cloud, with no manual download, no USB, and no data loss. All data will be transfer to Freshliance Cloud via WiFi or 4G network, with automated data access and tracking via the cloud platform and mobile APP.
This is ideal for automated, large-scale cold chain operations — especially for businesses managing multiple shipments daily.
Key Features and Benefits of Freshliance’s Logistics Monitoring Solutions
Real-Time Auto Upload
Temperature and humidity data sync automatically when the Bluetooth temperature monitors enter the range of a WiFi or 4G gateway — no manual operation required. This saves labor by eliminating the need for staff to manually collect or download data, making your cold chain monitoring more efficient and reliable.
Instant Alerts
Receive real-time SMS, email, or mobile app push alerts when temperatures exceed preset limits. This allows fast action to prevent product loss or spoilage.
High Accuracy & Certification
Our Bluetooth temperature sensors meet EN12830 and HACCP standards, providing high-precision readings and ensuring compliance for food and pharmaceutical logistics.
Scalable System Architecture
A single gateway can support up to 100 Bluetooth temperature sensors, making it ideal for managing large fleets or warehouse networks. Easily adaptable to the size and layout of your operation.
Cloud Platform & Mobile App Access
