Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  A | IPC G

Claim 7:
8. A solar radiation heat measurement method executed by a solar radiation heat sensor device, the solar radiation heat measurement method comprising:
a first step of measuring, by a temperature sensor, a first temperature of a first plate and a second temperature of a second plate, wherein the solar radiation heat sensor device comprises:
the first plate, the first plate having a black surface;
the second plate, the 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;
the temperature sensor, the temperature sensor being disposed in the casing; and
a processor, the processor being encased by the casing; and

a second step of calculating, by the processor, 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 in the first step.
