In this seminar, a novel approach to directly interface a capacitively-coupled resistive sensor to a microcontroller will be discussed. The existing measurement schemes for these series RC sensors are complex. Most of them employ synchronous demodulation approach that needs a precise sine wave excitation, multipliers and low pass filters. This level of complexity is acceptable when the value of resistance to be measured is very small. However, it will not be justified when one aims to scale the circuit for an array of sensors, or measure higher resistance values. The proposed simple measurement system constitutes of only a low-power microcontroller and a few passive components. It is capable of measuring both the resistance and the coupling capacitance. The coupling capacitance often also holds important data. A detailed analysis of the effect of the non-idealities on the resistance measurement showed that it is independent of the absolute value of the charging capacitor, supply voltage and pre-set threshold voltage used. The performance of the proposed scheme has been evaluated by building suitable prototypes. Initially, a setup was designed such that the measurement was not limited by the non-idealities of the microcontroller. The test results from this showed a maximum error of 0.28% and
