CMETER-RM is an EPC Class-1 Generation-2 (C1G2) RFID tag based on Farsens’ batteryless sensor technology. Built in a compact PCB format, the tag includes a dual channel capacitance meter. These RFID sensor tags are compatible with commercial UHF RFID readers (EPC C1G2). With a 2W ERP setup the battery-less capacitance meter can communicate to over 5 meters - 16 feet. The CMETER-RM can be customized with different antenna design and sizes, depending on the specific application. It can be encapsulated in an IP67 or IP68 casing for usage in harsh environments. It may also be possible to customize the specifications of the sensor upon request.
