The VMETER-DCLV10 from Farsens S.L., San Sebastián, Spain, 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. This 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. Evaluation kits are available.
