Measurement device, measurement system, measurement method, and program

A measurement device comprising:

• a sensor unit capable of measuring a state of a measurement target;
• and
• a control unit configured to control the sensor unit,
• wherein the sensor unit comprises:
• a measurement unit capable of measuring a voltage corresponding to the state of the measurement target;
• a first voltage comparison unit configured to determine whether or not the measured voltage is changed beyond a lower limit value of a predetermined voltage change;
• a second voltage comparison unit configured to determine whether or not the voltage change is changed beyond an upper limit value of the voltage change, and
• the control unit stops power supply to the sensor unit when it is determined in the first and second voltage comparison units that the measured voltage is not changed beyond the voltage change.

A measurement system comprising:

• a sensor device capable of measuring a state of a measurement target;
• and
• a control device configured to control the sensor device,
• wherein the sensor device comprises:

A measurement method comprising:

• a measurement step capable of measuring a voltage corresponding to a state of a measurement target;
• a first determination step of determining whether or not the measured voltage is changed beyond a lower limit value of a predetermined voltage change:
• a second determination step of determining whether or not the voltage change is changed beyond an upper limit value of the voltage change;
• and
• a stop step of stopping power supply to a sensor unit that measures the voltage when it is determined in the first determination step and the second determination step that the measured voltage is not changed beyond the voltage change.

A non-transitory computer readable medium storing a program therein, the program causing a computer to execute:

• a measurement function capable of measuring a voltage corresponding to a state of a measurement target:
• a first determination function of determining whether or not the measured voltage is changed beyond a lower limit value of a predetermined voltage change;
• a second determination function of determining whether or not the voltage change is changed beyond an upper limit value of the voltage change;
• and
• a stop function of stopping power supply to a sensor unit that measures the voltage when it is determined in the first determination function and the second determination function that the measured voltage is not changed beyond the voltage change.
