A sensing device comprising an electromagnetic sensor having a surface with a plurality of different electromagnetic radiation interception areas arranged one above the other, one or more controllable flaps adapted to cover one or more of the different electromagnetic radiation interception areas preventing the electromagnetic sensor from intercepting electromagnetic radiation on the covered electromagnetic radiation interception areas, at least one control mechanism adapted to maneuver the controllable flaps so as to change the covered electromagnetic radiation interception areas and a plurality of lenses located in front of the electromagnetic sensor, each having a different focal length. One of the lenses has a certain focal length and focuses electromagnetic radiation to at least one of the different electromagnetic radiation interception areas, and another of the lenses has a different focal length and focuses electromagnetic radiation to another electromagnetic radiation interception area.

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.

A solar monitoring system for measuring solar radiation intensity comprising a tracking unit having two-axis movement comprising, head mounted with first and second irradiation measuring units, and a controller. The first irradiation measuring unit comprises a direct normal irradiance (DNI) sensor and the second irradiation measuring unit includes a diffuse horizontal irradiance (DHI) sensor and a global horizontal irradiance (GHI) sensor. The controller receives inputs from the sensors or a software program configured to control orientation of the image capturing head so that the DNI sensor is always exposed to the sun, and the shading disc is always directly between the DHI sensor and the sun.

An image sensor, a camera module, and an electronic device are provided. The image sensor includes a pixel array and a control circuit. The pixel array includes a plurality of row pixels and a plurality of column pixels. The control circuit is configured to receive a first instruction to control an intersection region of a part of the plurality of row pixels and a part of the plurality of column pixels to detect an illumination intensity. The control circuit is further configured to receive a second instruction to control at least part of the pixel array to acquire an image.

The optical receiver includes a plurality of optical detecting units configured to convert an optical signal reflected from a target into an electrical signal and to output the electrical signal, a signal combiner configured to combine output signals of the plurality of light detecting regions, a plurality of switches provided between the plurality of optical detecting units and the signal combiner, and a controller configured to control the plurality of switches so that the plurality of optical detecting units are selectively connected to the signal combiner based on whether the optical signal to reflected from the target is input. Therefore, it is possible to make a module small, to improve stability and reliability, and to reduce a signal to noise ratio.

Systems (100) and methods (600) for acquiring data relating to an environment of interest. The methods comprise: receiving by a telescope (110) light scattered by an object within the environment; focusing a cone of light towards a spatial light modulator (112) which is placed a certain distance from the telescope on a telescope-focus surface; and deflecting a select amount of the cone of light by the spatial light modulator towards a photodiode array (114), whereby a sensitivity across the photodiode array is made uniform.

An optical sensor (10) includes a first switch (SW1) and a second switch (SW2), these switches are switched between a first step and a second step and thus the coupling of light receiving portions (photodiodes) and three analog-to-digital converters (ADCs) is switched. In the first step of the switch, photocurrents generated in a blue light receiving portion (BLUE), a green light receiving portion (GREEN) and a red light receiving portion (RED) are processed in real time. In the second step, photocurrents generated in an infrared light receiving portion (Ir), an environmental light receiving portion (CLEAR) and the green light receiving portion (GREEN) are processed. The photocurrents of the infrared light receiving portion (Ir) and the environmental light receiving portion (CLEAR) generated in the first step are calculated from a ratio of the two photocurrents measured in the green light receiving portion (GREEN).
