1. A computer-implemented method for monitoring an environment with a dynamically adjustable magnetometer, said method comprising:

  • periodically generating a first channel electronic signal representing a magnetic field of a monitored environment;

    periodically generating at least a second channel electronic signal representing said magnetic field of said monitored environment;

    summing an absolute value of said first channel electronic signal and an absolute value of said at least a second channel electronic signal over a period to generate a total value for said period;

    calculating a delta change between the total value for a first period and the total value for a second period; and

    generating an output if said delta change is greater than a pre-defined threshold.
