Temperature Monitoring using RFID Technology
|





|
RFID technology is ideal for temperature monitoring of goods in transit or storage.
Typical areas are: Cold chain distribution, frozen & refrigerated items. Transport
of blood, organs or vaccines. Laboratory sample analysis.
Temperature is monitored at user defined intervals. Upper and lower limits are set
to determine the acceptable temperature range.
There are various ways this temperature data can be utilised:
Traditionally an RFID reader (hand held or portal) is at the point of goods receipt
The data can be viewed on a PC or hand held, any problems are easily identified.
An RIFD portal can flash the tag LED if the temperature has gone out of scope.
This removes the need for user intervention, PC or hand held at goods receipt.
An in vehicle RFID reader warns the driver if a temperature problem is about to occur.
By utilising GPS & GSM technology, the temperature & location data is
transmitted back to a central office.
With an intelligent tag, scope and 'wake-up' temperatures are configured. If
during transit the temperature goes outside acceptable levels the tag LED
starts flashing. A temperature problem is then visually identified without the
need for any RFID hardware at the point of receipt.
