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.

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.

Abstract: To realize high-performance sensing and lower power consumption as well as to improve the entire operation of measurement. A terminal device according to the present invention includes a plurality of sensors for measurement measuring physical quantities of measurement targets, a storage unit storing information for determining activation manners of the plural sensors for measurement, a control unit switching all or part of the plural sensors for measurement from a non-activated state to an activated state based on the information when activated and an activation unit including a sensor for activation to be driven based on a change of environment and activating the control unit when a physical quantity having correlation with the physical quantity of the measurement target is satisfied as a given activation condition based on a detection result by the sensor for activation.

Abstract: To provide a terminal device realizing high-performance sensing and lower power consumption. A terminal device according to the present invention includes a sensor for measurement measuring a physical quantity of a measurement target, a control unit switching the sensor for measurement from a non-activated state to an activated state when activated and an activation unit driven in lower power consumption than the sensor for measurement and activating the control unit when a physical quantity having correlation with the physical quantity of the measurement target is satisfied as a given activation condition, thereby realizing high-performance sensing and lower power consumption.
