Abstract
A terminal device has measurement sensors for measuring physical quantities of measurement targets. A storage unit stores information determining a mode for activating the measurement sensors. Based on the information stored in the storage unit, a control unit switches all or part of the measurement sensors from a non-activated state to an activated state when the measurement sensors are to be activated. An activation unit includes an activation sensor driven on the basis of environmental changes. The activation unit is configured to activate the control unit on the basis of detection results from the activation sensor when a physical quantity correlated with the physical quantity of the measurement target satisfies a given activation condition.
