In a press release dated 7 December 2021, Avery Dennison announced the launch of AD TT Sensor Plus 2 BLE, an active temperature-logging sensor that utilizes Bluetooth and Near Field Communication technologies. The new product is designed to automate temperature data collection in cold chain logistics, such as the transportation and storing of agricultural goods, seafood, frozen food or pharmaceutical products.

Food waste is a global, multi-billion dollar problem, often caused by poor storage and care during transportation. Temperature fluctuations can interrupt cold chains which then opens the door to premature spoilage.

AD TT Sensor Plus 2 BLE is a cost-effective and system-agnostic temperature-logging solution that can help logistics managers to better 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 end customer.

The temperature logger combines a wireless near-field communication microchip (NFC) with a Bluetooth (BLE 5.1) microchip enabling the stored data to be extracted via a tap with an NFC-enabled smartphone, or automatically via a Bluetooth access point, such as Bluetooth beacons and mobile devices with bluetooth connection. It can be password protected for access and use and supports advanced encryption models where needed.

The sensor can be easily reprogrammed to suit particular applications, using a secure NFC link. This results in a single logger that can be reprogrammed with multiple setting options, and reused multiple times to prevent wastage.

Bluetooth long-life battery

Long-life battery, users have the ability to record up to 500,000 temperature records on the data logger for up to two years with proven real-time clock (RTC) accuracy. In real-world applications, this means that there is effectively no limitation on journey times, due to the AD TT Sensor Plus 2 BLE’s large memory and lifespan of up to two years.

In addition, this provides reliable and systematic transparency throughout the supply chain, without manual intervention. Bluetooth capability, any process can become more efficient through automated hands-off product tracking and data collection.

A user-friendly interface is available on various device platforms, including Cloud-based settings and storage (TTNet), plus 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) and are compliant with ISO 9001:2015 quality management and ISO 14001:2015 environmental management, which ensure a reliable and state-of-the-art product that meets a variety of logistic requirements, especially in the food and grocery retail industry. The RFID inlays are manufactured according to the industry’s highest quality standards.
