Multi-sensor

A device comprising:

• a housing;
• a plurality of first photosensors positioned in the housing and having a central axis, wherein each of the plurality of first photosensors has an angle of view oriented radially outward from the central axis, the angle of view of each of the first photosensors overlapping the angle of view of each of two respective immediately adjacent first photosensors;
• at least one light-diffusing element disposed around and in the field of view of the plurality of first photosensors;
• at least one second photosensor positioned in the housing and having an angle of view that at least partially encompasses a direction substantially parallel with the central axis of the plurality of first photosensors;
• an infrared sensor in the housing and configured to measure sky temperature, wherein the infrared sensor has an axis of orientation that is substantially parallel with the central axis of the plurality of first photosensors and faces outward from a top portion of the device during operation to measure the sky temperature based on infrared radiation captured from outside the device;
• and
• a power interface configured to receive power from at least one power supply that is configured to power the first plurality of photosensors;
• wherein the device is configured to send sensor data from the plurality of first photosensors, the at least one second photosensor, the infrared sensor, or a combination thereof, said sensor data used by a controller to control a tint of one or more electrochromic windows.
