Abstract

The idea behind the ThermoTag is the need to develop a complete passive tag with a simple circuit for measuring temperature. This paper focuses on the development of the tag which includes the proper designing of the antenna, which is very important for the passive development and also the measuring principle and the technique used for measurement. As a result a small and thin transponder (45 mm in diameter and 3.5 mm in thickness) is developed which is used for measuring temperature over a wide range. The transponder is one of its kinds because of its size, simplicity and by using a NTC helps to produce a “disposable passive sensor device”.
