AD TT Sensor Plus 2  [Sensor tag]

NFC for challenging cold-chain environments

Industry segment: Food, Healthcare, Logistics 

The AD TT Sensor Plus 2 is a small, low-cost temperature data logger. It can measure and log the ambient temperature for a period of up to three years. It fits easily into most medical or food packaging to monitor the storage and shipping environments to which products are exposed throughout the supply chain.

It uses a wireless near field communication (NFC) microchip so the stored data can be extracted and transmitted to a reader. The reader can be a PC equipped with a USB NFC Reader and the application software TTScan installed, or an NFC-enabled smartphone with the application TTApp. The internet accessible database TTNet completes the system. 

After activation, the AD TT Sensor Plus 2 registers the date, time (in UTC) and temperatures at programmable intervals. It can register up to 100,000 temperature events. Temperature alarm limits can be programmed into the tag, which can give warning signs when the tag is read.

Users of the AD TT Sensor Plus 2 system can view the detailed history of temperatures over a selected period of time. When logged on to the TTNet database, the logged temperatures and other data for a particular tag ID can be viewed. 

For security, the database can check whether the smartphone or PC running the TTApp are authorized to read information from the devices or to program the devices.

High security measures are taken to ensure that the data on the TT Sensor Plus 2 cannot be manipulated and the tag cannot be reprogrammed.
