Abstract: The present disclosure describes devices for detecting fine and ultrafine particulate matter. The devices may include at least one optical sensor configured at an angle of greater than 90 degrees from a direction of air flow, such that particulate matter is carried away from the sensor. In some examples, a device includes a housing, a light source and a light trap. The light source may be disposed within the proximal end of the housing and can be configured to direct a beam of light toward the distal end of the housing. The light trap may be disposed within the housing to reduce backscatter from the beam of light.

Abstract: The present disclosure is directed to an air quality monitoring system. The air quality monitoring system can include an interface, a memory in communication with the interface, and processing circuitry in communication with the memory. The interface can be configured to receive air quality information associated with an environment and the memory can be configured to store the air quality information associated with the environment. The processing circuitry is configured to detect, based on one or more transitions in the air quality information associated with the environment, an air quality event at the environment and output, via the interface, to an external device, a notification or remediation action associated with the detected air quality event at the environment.
