The VMETER-DCLV10, from Farsens, is a battery free RFID sensor tag capable
of transmitting a unique identifier and the associated voltage level
measurement data to a commercial EPC C1G2 reader without the need of a
battery on the sensor tag. The device can measure voltages in a range from
0V to 1.5V with an adjustable gain of 1-1000.

The VMETER-DCLV10 has a 96 bits EPC number, a 32 bit TID and a password
protected Kill command. The tag comes in a variety of antenna designs and
sizes to adapt the performance to the required application in the 860-960
MHz band. The reading distance for the battery-free thermistor tag is around
1.5 meters (5 feet) and it can be embedded in a wide variety of materials
such as plastics or concrete. It can also be encapsulated in an IP67 or IP68
casing for usage in harsh environments.

VMETER-DCLV10 tags offer R&D teams the opportunity of using proprietary
voltage based sensors in battery-free mode. The VMETER-DCLV10 provides
battery-free and wireless communication means to those companies looking for
this kind of solution. Typical voltage based sensors include load cells or
strain gages amongst others. Evaluation kits are available.
