Abstract

This paper presents a solar-powered wireless temperature sensor based on time-coded ultrawideband (UWB) radio frequency identification. A negative temperature coefficient resistor acts as the sensing element. It controls the current of a PIN diode connected to a UWB scattering antenna. The wireless sensor is self-calibrated using a narrowband tone, making its performance independent of the distance or orientation between the reader and the sensor. A consumption of 82 mu A is demonstrated. An error under 0.6 degrees C within a 35 degrees C-70 degrees C temperature range is obtained for most of the cases.
