Utilizing ratiometric voltage measurements and an adaptive tuning factor, the system effectively compensates for lead-wire resistance and diode mismatches. A prototype implemented with an ATmega2560 microcontroller demonstrates accurate resistance measurements in the range of 60- 320 Omega , corresponding to a Pt100 sensor, achieving an uncertainty error of less than 0.13% for a lead-wire resistance of 4.87 Omega and 0.15% for 10.0 Omega . Experimental results confirm the system's precision and reliability over long lead lengths, offering a cost effective and robust solution for industrial and remote sensing applications requiring accurate temperature measurements.This work was supported by Mahasarakham University.Institute of Electrical and Electronics EngineersDepartamento de ComunicacionesEscuela Politécnica Superior de GandiaMahasarakham UniversityUniversitat Politècnica de ValènciaRepositorio Institucional de la Universitat Politècnica de València Riunet20252025-05-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/221701reponame:RiuNet.
