摘要:
Various implementations relate generally to a multi-sensor device. Some implementations more particularly relate to a multi-sensor device including a ring of radially-oriented photosensors. Some implementations more particularly relate to a multi-sensor device that is orientation-independent with respect to a central axis of the ring. Some implementations of the multi-sensor devices described herein also include one or more additional sensors. For example, some implementations include an axially-directed photosensor. Some implementations also can include one or more temperature sensors configured to sense an exterior temperature, for example, an ambient temperature of an outdoors environment around the multi-sensor. Additionally or alternatively, some implementations can include a temperature sensor configured to sense an interior temperature within the multi-sensor device. Particular implementations provide, characterize, or enable a compact form factor. Particular implementations provide, characterize, or enable a multi-sensor device requiring little or no wiring, and in some such instances, little or no invasion, perforation or reconstruction of a building or other structure on which the multi-sensor device is mounted.

An optical sensor device comprises a first (10) and a second (15) optical sensor arrangement. In the first optical sensor arrangement (10) at least one optical sensor structure (11) measures the incidence angle of incoming light (θ) that is approximately on the main beam axis (20) of a light source (22). The second optical sensor arrangement (15) comprises at least one optical sensor structure (16) with at least one optical sensor (24), at least two metal layers (43,44) and opaque walls (26) optically isolating the optical sensor (24). An evaluation circuit (14) provides an output signal (46) of the second optical sensor arrangement (15) under the condition that the incidence angle (θ) measured by the first optical sensor arrangement (10) lies within a set interval.

摘要:
An optical sensor and an electronic device having an optical sensor. The optical sensor includes: an optical waveguide containing a photochromic material; a light emitter that emits visible light to be incident on the optical waveguide; and a light receiver that detects the visible light emitted from the light emitter and progressing through the optical waveguide. A transmittance of the optical waveguide in relation to the visible light may be changed by the photochromic material as the optical waveguide is exposed to UV light. The optical sensor and the electronic device having the same may be variously implemented according to exemplary embodiments.
