Classification: CPC G  A | IPC G

Claim 0:
1. A solar radiation heat sensor device, comprising:
a first plate having a black surface;
a second plate having a silvery-white surface;
a casing, wherein a first surface of the casing supports the first plate and the second plate in such a manner as to have the black surface and the silvery-white surface facing a same direction and exposed to an outside;
a first heat insulating material between the first plate and the first surface of the casing, wherein the first heat insulating material contacts a back surface of the first plate that is opposite to the black surface;
a temperature sensor in the casing and configured to measure a first temperature of the first plate and a second temperature of the second plate; and
a processor encased by the casing and configured to calculate a solar radiation heat amount based on a difference between the first temperature of the first plate and the second temperature of the second plate as measured by the temperature sensor.
