The temperature tracking and monitoring industry has a multi-billion-dollar economic and environmental impact worldwide. It is constantly changing and adapting to growing consumer demands. But to remain competitive and profitable, cold chain logistics fleets have to look for innovative and efficient solutions. Bluetooth technology, combined with vehicle GPS trackers and sensors, opens up new possibilities for fleet and cargo monitoring.

Solution description

To solve the challenges mentioned above, we use the SPECIAL category GPS tracker FMB140  or other FMB EYE Sensor - the brand-new BLE based Teltonika accessory with smart features and extensive functionality set including ID signal transmission, temperature, humidity, and internal battery level tracking.

How it works - the FMB models is based on the FMB platform and supports wireless Bluetooth LE connectivity, so it can effectively communicate with Bluetooth devices such as sensors. To ensure the best results, the tracker should be installed in a cold chain vehicle and configured the usual way in the spot where its Bluetooth antenna is not covered by bulky metal parts nearby.

The compact and lightweight EYE Sensor has to be attached to temperature-sensitive cargo items to be tracked and monitored - the protective bag, outer corrugated carton, container, barrel, pallet, etc. Vehicle GPS tracker receives readings from each sensor over the air at configurable intervals and sends this data as iBeacon or Eddystone profile to a server for analysis combined with the actual temperature, humidity, and its GNSS location details.

Dedicated software developed by a telematics service provider determines and displays all EYE Sensors (thus, tagged items) locations based on proximity to the vehicle tracker and the parameters they track. Because of that, the cargo of cold chain lorry can be monitored via PC, laptop or smartphone in real-time this way notably improving the efficiency of goods management, logistics operations and preventing losses or thefts. But we are not stopping there…
