The TRANS-LOGGER-B transportation conditions monitoring system comprises a set of devices and Android system software used for documenting transportation conditions of shipments. The system measures and records air temperature and relative humidity in cargo space or transportation packages. It is indispensable wherever there is a need to monitor a supply chain of products subject to climatic conditions - temperature and relative humidity.
The TRANS-LOGGER-B transportation conditions monitoring system consists of a set of devices with their own independent power supply:
The control point (e.g. a smartphone with Android 5.0 system or
later, with the TRANS-LOGGER-B
application installed) offers Bluetooth radio connection with air
temperature and relative humidity sensors. The control point with the
TRANS-LOGGER-B application concurrently serves up to 30 measuring
The control point display shows the current temperature and relative
humidity in particular locations, indicates when the alarm thresholds
are breached; and enables the measurement history to be viewed locally
in the form of charts.
When there is no connection with the sensors (e.g. the sensors have
been sent in packages with a different shipment, outside the range of
the control point), it is possible to re-write the measurement history
stored in the sensors whenever the connection with the control point is
The recorder stores measurements of the sensors in the memory of the TRANS-LOGGER-B
application, over the user’s pre-defined time intervals. If the radio
connection between the recorder and the sensors is lost, after
re-establishing a connection with the sensors, if requested the
recorder can retrieve the missing measurements from the sensors’
The recorder sets alarm thresholds (lower and upper limits for
temperature and relative humidity) that, when breached, can trigger a
number of signalling methods: on the display, by a sound alarm, a voice
or text message, or email, and indicates the occurrence in the report.
The report of the recorded transportation conditions may be printed on
a printer upon delivery and is stored in the memory in CSV and PDF
formats, which may be sent via email to a specified address.
The recorder also makes it possible to send ongoing recorded measurements via GSM mobile network to the
LBX Server software, installed in the central overseeing transportation on a Windows PC.
If the recorder is a terminal with an Android system with an integrated printer (e.g. Cilico CM550, PDA-3505-A or GC068 types), then — similarly to any other tablet or smartphone — additional client applications may be installed, connected for example, with transportation logistics. If the recorder is a specialist terminal (e.g. Symbol TC55 Zebra) or any other tablet or smartphone, then the external printer (e.g. RPP-02N) is connected to it via Bluetooth and may also be used to print other client documents.
The air temperature and relative humidity measuring sensors — that is
LB-518 BLE-LOGGER wireless temperature and humidity recorders
— are independent devices with their own battery power supply. The
power supply is sufficient for approx. 12 months of uninterrupted
operation provided that the recording interval is set to 1 minute. It
is possible to replace the power source—i.e. the typical 3 V batteries
LB-518 temperature and humidity sensors
transmit measurement data to the recorder wirelessly. The sensors are
also recorders and feature their own permanent data storage facilities,
in case there is no connection with the recorder or the recorder
Measurements are taken to the value of 0.1°C for temperature and
0.1% for humidity. The minimum number of recordings stored in the
memory of each of the sensors is 15,000 temperature and humidity
measurements. When a sensor memory is full, the oldest measurements are
overwritten by the newer ones.
The temperature and humidity sensors feature installation holes for
easy mounting and dismounting inside the vehicle’s cargo space or
LB-518 BLE-LOGGER temperature and humidity sensors, as per order, may feature an individual calibration certificate for the required measurement points, issued by the
accredited LAB-EL Calibration Laboratory. Periodically, the sensors may be subject to re-calibration in the Laboratory, in order to confirm their correct functioning.
The recorder in the driver’s cabin may be any smartphone or tablet with an Android 5.0 system or later with the specialist TRANS-LOGGER-B application installed. The application provides all the functionalities of the TRANS-LOGGER-B system described above.
