Abstract

In this paper, we present a passive ultra high frequency (UHF) radio frequency identification (RFID) magnetic field sensor system. The system consists of a sensor transponder (tag), which detects a magnetic field above a certain threshold by means of a reed switch connected to a one-bit sensor interface of a state-of-the-art UHF RFID chip. In addition, the system allows localizing of the sensor tag by means of direction of arrival (DoA) estimation implemented at the UHF RFID reader. In an application example, the reed switch is triggered by a permanent magnet, which is attached to the on/off switch of a solder station, thus allowing detection of its switching status and location. We investigate the influence of the tags sensing state on the localization capability and the tag wake-up power. The conducted measurements show that the sensing state has an insignificant influence on the accuracy of DoA estimation, but has a significant influence on the wake-up power.
