Abstract
Inferring building metadata from distributed sensors is described. In an embodiment multiple sensors are situated at various locations in a building detecting physical quantities (e.g. light, heat, motion). The data from at least one sensor is analyzed in order to detect events occurring in proximity to the sensor. Data about an event detected at a first sensor is compared with events detected at other sensors in order to identify correlated events from which connections between the sensor locations can be inferred and a building layout generated. In some embodiments a threshold may be applied to the data in order to filter out false events. In some embodiments the building layout may be used as part of a building control system. In some embodiments the sensor data may be used to determine if the sensor has been moved.
