What steps have to be followed for interfacing a sensor to a microcontroller 8051?

(a) make the appropriate connections with the controller, ADC conversion, analyse the results

(b) interface sensor with ADC and ADC with 8051

(c) interface sensor with the MAX232, send now to microcontroller, analyse the results

(d) none of the mentioned

This question was addressed to me by my school teacher while I was bunking the class.

The origin of the question is Sensor Interfacing in chapter 8051 Microcontroller of Microcontroller

Right answer is (b) interface sensor with ADC and ADC with 8051

Explanation: For interfacing a sensor with an 8051 microcontroller, we need ADC in between because output of sensor is analog and microcontroller works on digital signals only. So whatever signal generated by the sensor is converted into its digital equivalent using ADC and equivalent digital signal is given to the microcontroller for processing.
