ABSTRACT

A new design about the integration of temperature sensor and RFID tag is provided. This is a dual-tag design, in which the temperature element is connected to one of the RFID tag antennas to form a parallel structure. In this design, some of the functions of the sensor are transferred to the RFID reader so that some components of the sensor can be cut, reducing the production costs of existing design. By defining the signal strength of the first tag as a reference value, the problem of setting a standard is solved in the temperature detection process. RF module can be used to make the energy transformation without requiring the entire design to have an external continuous power source to provide energy. In addition, experimental data proves the feasibility of this design.
