Farsens released R-Meter, passive RFID ohmmeter designed to allow other companies to develop custom EPC Gen 2 RFID sensors based on any resistance-dependant transducers that meet their specific application requirements at best.  

R-Meter

R-Meter works as an interface between any resistance-dependant sensor without wireless transmission and any EPC Gen 2 RFID reader, making it possible to retrieve the measured resistance values along with the associated unique tag ID. The product can be used in combination with resistance-dependant transducers as thermistors, LDRs, soil moisture sensors or strain gages and get them work battery-free. The measurable resistance values range from 10 ohms to 10 megaohms, with accuracy of ±3% from 100 ohms to 500 kiloohms and of ±7% out of this range. R-Meter can be embedded in non-metallic materials and can be delivered with fully customized encasements to meet any requirement in terms of durability and mounting options. R-Meter can work without batteries with typical read range of 1.5 meters, though can operate also in battery-assisted mode with extended read range. The tag is available in various versions with different directivity.
