Abstract: A measurement device includes: a data acquisition unit that measures a sensor detection value by a sensor in at least two operation modes including a first mode with low power and a second mode for operating at a high speed, transmits a trigger signal when the detected value exceeds a first threshold value while operating in the first mode, transmits a first notification signal notifying that the user has started walking when the detected value has exceeded a second threshold value while operating in the second mode, and starts measuring gait data including a walking characteristic of the user wearing the sensor based on the sensor detection value; and a control unit that switches the operation mode to the second mode when the trigger signal is received, and switches the operation mode to the first mode when a predetermined condition is satisfied after reception of the first notification signal.
