Abstract: A distributed security system includes a detection unit disposed at a first location. The detection unit includes a particle sensor that is configured to detect a particle count in first location. The detection unit also includes a housing enclosing a portion of the particle sensor. The security system also includes a camera disposed at a second location and having a field of vision encompassing the first location. The camera is configured to capture a video of the first location. The system also includes a server communicatively connected to the detection unit and the camera and configured to associate the particle count with the video.

Abstract: A personal air quality detection device is configured to monitor the air quality of a user based on the location of the personal air quality detection device. To this end, the personal air quality detection device first determines a location of the user. Based on the determined location, the personal air quality detection device selects a location profile associated with the determined location indicating one or more substance threshold values. Using a substance threshold value indicated by the location profile, the personal air quality detection device monitors the location for a substance of interest by comparing a measurement of the substance of interest to the substance threshold value. Based on the comparison, the personal air quality detection device displays one or more notifications associated with the substance of interest.

Abstract: A vaporized aerosol detection system is presented herein. The system can include a motion sensor that is configured to detect movement in a predetermined or desired area. Further, the motion sensor can be configured to generate a detection signal in response to one or more detected objects in the area. The system can also include a particle sensor electronically coupled to the motion sensor. The particle sensor can be configured to detect a particle count of the area when the objects are detected by the motion sensor. Further, the system can include a housing configured to enclose at least a portion of the motion sensor and particle sensor.

Abstract: An air quality monitoring system integrated with the building management system observes and records air quality data and building system data. Based on the observed air quality data and building system data, one or more training data sets can be generated. Such training data sets are used to train one or more machine-learning models configured to determine one or more threshold values for the air quality. These thresholds are then used to modify or adjust one or more building systems based on monitored air quality data.
