The EELOG is a ruggedized, semipassive RAIN RFID temperature logger tag that allows to monitor temperature sensitive products like pharmaceuticals, industrial chemical products and perishable foods during transportation and storage. The combination of the high resolution sensor, the large memory size and the standard RFID interface permits to realize effective track and trace solutions for the cold-chain.
The EELOG can be used with standard RAIN RFID readers available on the market without requiring any additional equipment.
The tag can be configured to store temperature samples in intervals from 8 second to 18 hours in the internal memory that can contain up to 8,000 samples. The user can define alarms for high and low temperature thresholds for an accurate control of the temperature excursions.
The rugged enclosure of this logger make it the perfect choice for the cold-chain monitoring in harsh environment with extreme temperatures or in presence of strong vibration.
The EELOG logger can be used for multiple shipments thanks to the long battery life and the reset function thus allowing to reduce the total cost of the solution and anticipate the ROI.
