Bluetooth temperature data loggers
BTT01 and BTT02 are reusable Bluetooth temperature data loggers that we build for cold chain monitoring. They feature BLE 5.0 low-power broadcast, high-precision temperature sensing and local data storage for audit-ready temperature records. We design the BTT01 as a cost-effective compact temperature beacon for standard temperature tracking.It focuses purely on temperature sampling, with configurable sampling intervals and over-temperature alarms, and it pairs easily with our mobile APP or BLE gateway. It is widely selected for bulk pallet monitoring and regular refrigerated transport when you only need temperature history. The upgraded BTT02 adds a built-in light sensor to detect package opening and tampering events, comes with larger data memory and an ultra-thin form factor. It is the right choice for shipments that require both temperature logs and light exposure records.
These Bluetooth temperature loggers support flexible parameter setup, automatic temperature alarm triggers and one-click data export to PDF or Excel for shipment traceability. Both models work with our Beacon cloud APP and cloud platform, enabling real-time temperature viewing, historical curve review and OTA remote configuration. They can also integrate smoothly with our 4G GPS trackers to combine location tracking and temperature logging, delivering a complete end-to-end cold chain telematics solution for shipment-level visibility. IP65 waterproof casing protects the loggers from moisture and dust inside refrigerated trucks, cold rooms and shipping containers.
Choose BTT01 if your monitoring task only requires temperature tracking. It offers a budget-friendly option for groceries, dairy and general refrigerated goods, helping you cut monitoring costs for large-volume shipments.
Select BTT02 when you need extra tamper detection beyond temperature monitoring. The light sensor records every instance of package exposure, which is critical for high-value sensitive cargo such as biologics, premium seafood and temperature-sensitive medical supplies, where unauthorized package opening is a major risk.
With long battery life and simple wireless deployment without wiring, these BLE temperature loggers are great alternatives to disposable single-use loggers. They fit stationary cold storage, refrigerated fleets and cross-border cold freight across North America and Europe. Whether you manage a small local cold delivery business or a large-scale international logistics network, BTT01 and BTT02 provide scalable, reliable Bluetooth temperature logging solutions to reduce product spoilage and simplify temperature traceability.
