1. A detector, comprising:

  • a detecting device that detects a proximity condition and develops a parameter of electric power related thereto; and

    a parameter measuring device coupled to the detecting device including;

    a parameter detector having a current mirror,an analog-to digital converter (ADC) coupled to the parameter detector, the ADC including a plurality of operational ranges and operative in one of the plurality of operational ranges to develop a digital representation of the parameter, anda range selector coupled between the ADC and the parameter detector and operative to cause the parameter detector to develop an output signal magnitude representative of the parameter of electric power wherein the output signal magnitude is within one of the operational ranges of the ADC.
