2. System Overview
LIBERO Gx real-time data loggers are used for temperature monitoring, particularly in the transportation sector. The measured data is transmitted via LPWA cellular technologies (LTE-M and NB-IoT) to the monitoring software (elproCLOUD or liberoMANAGER). The software stores and analyzes the data, automatically generates alerts in the event of temperature excursions, and creates reports. The system provides excellent transparency and traceability to ensure compliance with GxP requirements.
