Automatic power-supply apparatus for wireless sensing nodes

The invention discloses an automatic power-supply apparatus for wireless sensing nodes. By adoption of the automatic power-supply apparatus, solar energy, wind energy and temperature difference can be comprehensively utilized, and the miniaturization of the apparatus can be satisfied. The automatic power-supply apparatus adopts a spherical framework; the automatic power-supply apparatus comprises a dome-shaped top cover and a bottom plate; multiple air guiding sheets are uniformly and vertically mounted between the top cover and the bottom plate; top solar cell panels are arranged on the upper surface of the top cover; top temperature-difference power generation chips are mounted on the back surfaces of the top solar cell panels; a perpendicular wind power generator is mounted in the middle of the spherical framework; the air guiding sheets, the lower surface of the top cover and the upper surface of the bottom plate form air channels; air channel opening solar cell panels are mounted on the lower surfaces of
