Measuring device

A measuring device comprising:

• at least two magnetic sensors capable of selectively measuring a magnitude of a component in a specific direction of a magnetic field, the at least two magnetic sensors being arranged lined up in the specific direction, the specific direction being a specific single linear direction;
• a processor;
• and
• a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising:
• repeatedly acquiring, at a plurality of timings, a measurement value indicating the magnitude of the magnetic field detected by each of the at least two magnetic sensors;
• identifying the measurement value having the largest absolute value, from among at least two measurement values acquired at a specific timing from each of the at least two magnetic sensors;
• identifying a first magnetic sensor that has detected the identified measurement value having the largest absolute value;
• and
• identifying, based on a time change in the acquired measurement value, a distance in an orthogonal direction that is orthogonal to the specific direction, between an object to be measured and the identified first magnetic sensor.
