SENSOR DEVICE FOR MEASURING A DIRECTION ALONG WHICH LIGHT OF A LIGHT SOURCE, PARTICULARLY OF THE SUN, IMPINGES ONTO THE SENSOR DEVICE AS WELL AS FOR MEASURING THE INTENSITY OF THE LIGHT FROM SAID DIRECTION

摘要

The invention relates to a sensor device (1) for measuring a direction of a light source, particularly of the sun, comprising: at least a first and a second photosensitive element (P1, P2), wherein each photosensitive element (P1, P2) comprises a photosensitive surface (S1, S2) for detecting light (L) impinging on the respective photosensitive surface (S1, S2), and a substrate (20) for carrying said at least two photosensitive elements (P1, P2), wherein the substrate (20) comprises a front side (20a) and a back side (20b), which back side (20b) faces away from the front side (20a). According to the invention, said substrate (20) is designed to shade the photosensitive elements (P1, P2) depending on said direction to be estimated.
