Farsens Unveils Battery-Free RFID Tag
Battery-free tag reading system.
San Sebastian, Spain — The RMETER from Farsens S.L. is a battery-free RFID sensor tag capable of transmitting a unique identifier and the associated resistance measurement data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag. This device can measure resistances in a range from 100Ω to 500kΩ with an accuracy of ±3 percent. It also offers an extended operation range from 10Ω to 10MΩ with an accuracy of ±7 percent.

The RMETER has a 96 bit 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 860-960MHz 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 and concrete. It can also be encapsulated in an IP67 or IP68 casing for usage in harsh environments.

The RMETER can be used without batteries at all, allowing for a wide range of opportunities monitoring resistance in applications where the accessibility is restricted, or where the use of batteries is not recommended.

Typical resistance-based sensors include thermistors, Light Dependent Resistors (LDRs), soil moisture sensors and strain gages.
