Direct solar radiation captured by a rotating reflector is guided to a pyroelectric element with flat spectral sensitivity, and direct solar radiation can be measured simply by pulse signals.
Since direct insolation can be measured, it is possible to calculate horizontal plane scattering insolation by combining with a global insolation meter.
