A full passive RFID tag that measures voltage level of the device connected to it with a 0V to 1.5V range
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.
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.
Farsens designs and manufactures full passive RFID sensor solutions. Their proprietary UHF RFID IC allows Farsens to develop long range solutions for asset tracking – via the unique ID – and monitoring – via the attached sensor – without the need of any battery on the tag.
