Abstract: Provided is a sensor apparatus including: a normal operation unit including a first sensor and a storage device; an external environment detection unit including a second sensor; a power supply switch unit configured to control supply of electric power to the normal operation unit; and a power supply configured to supply the electric power to the normal operation unit via the power supply switch unit. In the sensor apparatus, in an operational mode, the normal operation unit records data measured by the first sensor into the storage device, and, in a non-operational mode, when a measured value obtained by the second sensor satisfies a predetermined condition, the external environment detection unit controls the power supply switch unit so that the power supply switch unit supplies the electric power to the normal operation unit, and the normal operation unit records the data measured by the first sensor into the storage device.
