Abstract

The embodiment of the invention discloses a radio frequency identification devices (RFID) sensing device. The device comprises a baseplate and an antenna which is arranged on one side of the baseplate, wherein the antenna comprises a first antenna, a second antenna and a thermosensitive capacitor, the first antenna and the second antenna are arranged in parallel, and a gap is left between the first antenna and the second antenna; and the thermosensitive capacitor is connected on the first antenna in series. The RFID sensing device not only can be substituted for RFID tags in the current market, but also does not need integrated circuit (IC) chips, has a sensing function, is low in cost, and is convenient to popularize and use.

Description

technical field [0001] This application relates to the technical field of RFID, and more specifically relates to a simple RFID sensing device. Background technique [0002] The RFID passive tags currently used in the industry are composed of an antenna and an IC chip in terms of electrical performance, plus packaging. [0003] Taking a 920-925MHz industrial card label as an example, the processing cost of the antenna is about 0.2 yuan, the cost of the IC chip is 0.4 yuan, the connection cost of the antenna and the chip is 0.05 yuan, and the cost of packaging and die-cutting, surface printing, and packaging It is 0.2 yuan. Therefore, the final cost of a work card label is: total material price + processing cost = 0.85 yuan. This causes the cost of existing labels to be too high, making it inconvenient to popularize and use. [0004] In addition, in many project applications, when the existing RFID passive tags are used, the IC chip can only simply read or store data, and ...
