Abstract
A terminal device has at least one measurement sensor for measuring a physical quantity of a measurement target. A control unit switches the measurement sensor, when activated, from a non-activated state to an activated state. An activation unit, which is driven at lower power consumption than the measurement sensor, activates the control unit when a physical quantity having a correlation with the physical quantity of the measurement target has satisfied a given activation condition.
