Abstract

A sensor (50) for determining the magnitude and intensity of solar radiation. The apparatus includes a diffuser (2) which provides radiation through channels (60a, 60b, 60c, 60d) within an elongated channeled member (5) onto photodiodes (54a, 54b, 54c, 54d). Each photodiode (54a, 54b, 54c, 54d) is optically isolated from other photodiodes. The diffuser (2) is arranged and constructed so as to receive radiation within 360 degrees of the surrounding environment.
