Direct resistive sensor interface to a microcontroller has several advantages but has one
prominent disadvantage, namely, the measurement is affected by the resistances of: 1) wires …

Output of a typical Wheatstone bridge, when it is connected to measure from a single or a
dual resistive element, possesses non-linear characteristic. This paper presents a novel …

A microcontroller-based digital hygrometer system using a low-cost moisture sensor in the
range of 3.7-100 ppm has been developed. The sensor is of capacitive type and consists of …

This paper presents a low-cost interface circuit for lossy capacitive sensors. Most of the
capacitive sensors are lossy in nature, where the resistance value of the sensor significantly …

Most of the resistive sensors have a large baseline resistor and a relatively small
incremental change in the resistor value due to the measurand. A half-bridge-based …

This article proposes simple relaxation-oscillator-based digital interfacing schemes for
resistive sensors in single-element and quarter-bridge forms. The proposed interfaces …

A novel readout circuit for interfacing single element resistive sensors is presented in this
paper. The proposed scheme is based on a new relaxation oscillator (RO). The RO, along …

A novel dual-slope resistance to digital converter (RDC) for compensating lead resistance is
presented. The RDC uses a dual-slope analog-to-digital converter (ADC) structure along …

An improved digital interface circuit for resistive sensors is proposed in this paper. The circuit
