Battery-free RFID tag measures voltage levels
A battery-free RFID sensor tag has been introduced by Farsens. The VMETER-DCLV10 can transmit a unique identifier and the associated voltage level measurement data to a commercial EPC C1G2 reader without a battery on the tag. The sensor tag can measure voltages from 0 to 1.5V with an adjustable gain of 1-1000.
The VMETER-DCLV10 has a reading distance of around 1.5m (5ft) and it can be embedded in a variety of materials such as plastics or concrete. It can also be encapsulated in an IP67 or IP68 casing for use in harsh environments.
The RFID sensor tag features a 96-bit EPC number, a 32-bit TID and a password protected Kill command. It is available in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960MHz band.
Evaluation kits are also available from Farsens.
