Hardware and Software Implementation Aspects for Low-cost Multi-Channel Interface for Passive Resistive Sensors

Abstract

<p><span lang="EN-US"><span style="font-family: Calibri; font-size: small;">The paper elaborates the hardware and software design and implementation aspects of a low-cost multichannel interface for passive resistive sensors. The interface is based on a multivibrator in a monostabile configuration and is suitable for direct interface to a programmable devices (e.g. microcontrollers, field programmable gate arrays, etc.). In the paper, details concerning the sensor interface are presented, and different calibration techniques are described. The theoretical analysis is supported by a practical realization of a prototype multichannel resistive sensor interface and software implementation in a LabVIEW environment.</span></span></p>
