Avery Dennison develops temperature-logging sensor

According to the company, food waste is a global, multi-billion-dollar problem, often caused by poor storage and care during transportation. Temperature fluctuations can interrupt cold chains and cause premature spoilage. 

AD TT Sensor Plus BLE is a system-agnostic temperature-logging technology, which can help logistics managers to monitor and protect the goods they are shipping, ensuring that they remain within a specific temperature range from the production phase to their delivery to the customer.

The temperature logger combines a wireless NFC microchip with Bluetooth (BLE 5.1), enabling the stored data to be extracted via a tap with a smartphone or automatically via Bluetooth beacons and mobile devices. It can be password protected and supports advanced encryption models where needed.

The sensor can be easily reprogrammed using a secure NFC link. This results in a single logger that can be reprogrammed with multiple settings and reused numerous times to prevent wastage. 

Thanks to its long-life battery, users can record up to 500,000 temperature records on the data logger for up to two years with proven Real-Time Clock accuracy. This provides reliable and systematic transparency throughout the supply chain without manual intervention. And thanks to the Bluetooth capability, any process can become more efficient through automated, hands-off product tracking and data collection.

An interface is available on various device platforms, including cloud-based settings and storage (TTNet), a free-of-charge app (TTApp both for iOS and Android) for NFC-enabled smartphones.

AD TT Sensor Plus 2 BLE inlays have a small footprint (70mm x 32mm). They are compliant with ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management to meet logistics requirements, especially in the food and grocery retail industry.
