en.Wedoany.com Reported - On June 2, China's Shenzhen Eelink Communication Technology released the BTT02 ultra-thin BLE 6.0 temperature data logger. Designed for cold chain transportation, pharmaceutical logistics, food delivery, warehouse monitoring, and other temperature-sensitive supply chain scenarios, this product features a reusable design to enhance temperature data retention and anomaly tracking capabilities for goods during transport and storage.
The BTT02 has a thickness of 2.4mm and can be placed flat inside packaging, attached to the surface of cartons, or deployed on pallets, in cold storage zones, and in refrigerated vehicles. Compared to traditional USB temperature data loggers that only read data after arrival, this device supports both local data recording and Bluetooth Low Energy broadcasting. On-site personnel can access historical data via the BeaconCloud mobile app, or pair it with Eelink's tracking devices equipped with BLE gateway capabilities to upload temperature, light, and alarm information to the cloud. For goods such as pharmaceuticals, vaccines, biological products, clinical samples, fresh produce, seafood, dairy products, and frozen foods, the focus of cold chain monitoring has shifted from "whether the destination is reached" to "whether temperature control requirements are continuously met throughout the entire transport process." The BTT02 provides a more granular data foundation for quality review, liability determination, and internal auditing through exportable temperature records, alarm evidence, and time curves.
The device supports a measurement range of -20°C to +60°C with a temperature accuracy of ±0.2°C and can store up to 100,000 readings locally.
From a technical configuration perspective, the BTT02 features a built-in light sensor that can detect box opening or exposure events, and supports temperature alarms, light alarms, and low battery alerts. It uses the Nordic nRF54L10 BLE 6.0 chip, with a Bluetooth broadcast range of up to 500 meters in open environments. The 1000mAh battery can support up to approximately 3 years of use under normal operating conditions, and the device body has an IP67 protection rating, making it suitable for repeated deployment in cold chain, warehousing, and logistics environments. The BeaconCloud platform supports configuring collection intervals, storage intervals, Bluetooth broadcast intervals, alarm thresholds, and device parameters. Historical data can be exported in PDF or CSV format, facilitating use by enterprises during goods handover, customer claims, quality release, and compliance archiving. For cold chain operators, the value of such devices lies in transforming single-point inspections into continuous data recording, and reducing reliance on manual inspections through Bluetooth and gateway integration.
Eelink stated that the BTT02 is now open for evaluation, sample requests, and commercial deployment. The company has long been engaged in the development of GPS tracking devices, wireless sensors, and IoT visualization solutions, with products covering fleet management, asset tracking, cold chain monitoring, and supply chain visualization. As cross-border pharmaceutical logistics, fresh food delivery, and temperature-controlled warehousing demand higher data traceability, cold chain equipment is evolving from single-purpose positioning terminals to a combined capability of "positioning, temperature, light, alarm, and cloud reporting." Low-power Bluetooth sensors are also becoming essential foundational devices in the supply chain IoT.
