This paper presents a low-cost interface for high-value resistive sensors varying over a wide range, from kOhm to GOhm . The proposed circuit that acts as a "resistance to period converter" is suitable to be interfaced to a microcontroller or a counting device. The behavior of real electronic components that produce estimation errors, is taken into account. Experimental results obtained by the realized prototype show a good resolution and repeatability.

Abstract

This paper presents a low-cost interface for high-value resistive sensors varying over a wide range, from kOhm to GOhm . The proposed circuit that acts as a "resistance to period converter" is suitable to be interfaced to a microcontroller or a counting device. The behavior of real electronic components that produce estimation errors, is taken into account. Experimental results obtained by the realized prototype show a good resolution and repeatability.
