Security added to Bluetooth temperature monitor

DeltaTrak announced the addition of a data security feature to its FlashLink Bluetooth Low Energy wireless monitor at last week’s PMA Fresh Summit in New Orleans.
“With the new security feature, shippers have the option to require receivers to enter an access code before they can see or download data from the BLE loggers,” said Frederick Lu, president and CEO of California-based DeltaTrak. “This gives them that extra layer of data security.”
A smartphone app sends information from a mobile device to the BLE web application where it can be viewed remotely by authorised users.
This is suitable for applications such as round-the-clock facility monitoring, pre-cooling operations and delivery routes. With the FlashLink loggers, users have secure access to data, immediate alert notifications, and reports in PDF and CSV formats.
The logger helps suppliers maintain continuous visibility of temperature and humidity during facility monitoring and pre-cooling operations. It is especially suitable for round-the-clock facility monitoring, such as cold storage warehouses, distribution centres, greenhouses, temperature controlled processing, and packing and staging areas. Alert notifications are sent to personnel so they can take quick corrective action before products are compromised by changes in temperature.
It should let pre-cooling operations improve efficiency, increase pallet throughput and extend product shelf life. The loggers monitor produce in cooling tunnels and when required temperatures are reached alerts are sent via email or SMS notifications. Instead of pre-cooling based on time and relying on staff to take pulp temperature, this automates tracking and provides real-time temperature conditions during the process.
Data can be analysed by personnel to identify strengths and weaknesses of their operation, and assure that products are adequately cooled, while eliminating the problem of pallets not being cooled long enough.
For delivery routes, receivers can also read temperature history data from the logger without opening the vehicle doors or locating the logger inside the truck. As soon as a vehicle arrives, the smart phone application accesses data from the logger from up to 30m away, so information is available immediately upon arrival.
Settings are customisable, including device name, logging interval, and high and low alarm limits. All data are available in the cloud, where temperature and location are reviewed remotely for tracking shipments in progress, making cold chain management decisions and reports for audits, HACCP and FSMA documentation.
