A direct resistive sensor interface to a microcontroller reported earlier, works well only if the sensor element is very close to the micro-controller pins. If the sensor element is at a distance from the micro-controller then the lead resistance due to connecting wires between resistive sensor element and the micro-controller introduces appreciable errors in the output. A modified scheme of direct sensor interface to micro-controller is presented here. In the proposed scheme, the effect of

A dual slope direct digital converter (DSDDC) suitable for resistive sensor elements already connected in a bridge form is presented. A conventional dual slope analog to digital converter (DS-ADC) is altered with an intentionally introduced instrumentation amplifier (INA) to realize the proposed DDC. The DSDDC accepts bridge connected resistive sensor elements as input and provides a digital output that is proportional to the quantity being sensed by the sensor elements. The results obtained
