By combining RFID with sensor technology the number of applications seems endless. The contactless RFID technology is then able to monitor various physical conditions during the shipping or production process of goods. Integrating sensor technology with RFID makes it possible. Advantages towards conventional monitoring systems indicate that user can highly benefit from these systems.
With an RFID sensors the user could measure the following physical conditions:
- temperature
- acceleration
- pressure
- extension
- humidity
Example applications for the use of RFID and sensors monitoring the temperature are:
- strict observance of the cold chain for food
- monitoring the freshness of flowers
- preservability and cooling of blood and pharmaceuticals
- Electronic components
Example applications for the use of RFID and sensors monitoring acceleration are:
- strict observance of sensible goods where thrown in the warehouse or during the shippment
- monitoring if pallets fell of the forklift during the transport
- monitoring the acceleration speed of vehicles in traffic
Example applications for the use of RFID and sensors monitoring the pressure are:
- monitoring tyre pressure in combination with the automotive engineering
- cylinder pressure measurements during engine production process
Example applications for the use of RFID and sensors monitoring the humidity are:
- RFID Chips can be bricked into walls or into hollow spaces to constantly monitore the humidity. Interesting in the field of construction because of the long term responsability/warranty of the manufacturer.
Advantages of RFID with sensor technology
- safety against manipulations
- transponder are available in nearly every shape and size
- transponders, batteries and components are well cased and protected against destruction
- ideal for specialty goods, that have to be shipped abroad and with a lot of repackeging involved
- Most RFID chips are heat- andcold-resistant (from circa. -70 up to 150 Degrees Celsius)
