A power source device for sensor nodes of a USN(Ubiquitous Sensor Network) is provided to continuously store electricity generated from a solar battery in a secondary battery and to stably supply the low current electricity. A power source device for sensor nodes(400) of a USN includes a solar battery(100), a secondary battery(200), and an interface circuit(300). The solar battery(100) has a self-generation function. The secondary battery(200) stores electricity generated at the solar battery(100), and supplies the electricity to the sensor node(400) of the USN. The interface circuit(300) connects the solar battery and the secondary battery(200). The solar battery, the secondary battery, and the interface circuit are mounted on the sensor node. |
