1. A portable device for collecting a plurality of different types of sensed physical data, comprising:

  • a portable unit sized for hand-held use, including;

    a housing;

    processor means mounted within the housing for controlling input and output of information corresponding with and according to a plurality of different types of sensed physical data to and from a memory means mounted within the housing for storing said information;

    operator control means for controlling the processor means; and

    a plurality of commonly configured externally accessible input ports extending through the housing that are connected to the processor means; and

    at least one sensor means for providing a sensed signal representative of a corresponding type of sensed physical data, wherein the sensor means comprises an interconnection means supportably connectable to the externally accessible portion of any of said input ports for providing to the processor means the sensed signal, the interconnection means comprising;

    (i) a data identification means for communicating to the processor means a data identification signal identifying the corresponding type of sensed physical data represented by the sensed signal; and

    (ii) a scaling means for altering the strength of the sensed signal to a corresponding predetermined scaling factor for calibrating the sensed signal into said information;

    wherein the processor means automatically employs said data identification signal and controls the input of the corresponding said information to said memory means according to the corresponding type of sensed physical data regardless of which of said plurality of input ports is connected to said interconnection means.
