The solution is based only on a (already existing in the system) microcontroller and a simple sensor interface circuit working as a voltage divider consisting of a reference resistor and a resistive sensor connected in parallel with an interference suppression capacitor. The measurement method is based on stimulation of the sensor interface circuit by a single square voltage pulse and on sampling the resulting voltage on the resistive sensor. The proposed solution is illustrated by a complete application of the compact smart resistive sensor used for temperature measurements, based on an 8-bit ATxmega32A4 microcontroller with a 12-bit ADC and a Pt100 resistive sensor. The results of experimental research confirm that the compact smart resistive sensor has 1°C resolution of temperature measurement for the whole range of changes of measured temperatures.}, type={Artykuły / Articles}, title={An Implementation of a Compact Smart Resistive Sensor Based on a Microcontroller with an Internal ADC}, URL={http://www.journals.pan.pl/Content/90405/PDF/10.1515-mms-2016-0020%20paper06.pdf}, doi={10.1515/mms-2016-0020}, keywords={microcontrollers, resistance measurement, ADC, time-domain measurements}, }
