Abstract: A handheld or mountable air measuring device includes a sensor assembly with sensors that measure airspeed simultaneously in two directions that are perpendicular to each other. The device includes a data protocol conversion board allowing the communication between the sensor assembly and a smart device included with or associated with the device. The smart device receives the airspeed data. The smart device includes a user interface that includes a map or layout of the environment within which the device is used. The data is displayed on the smart device on the map. The data can be processed locally or transmitted to a remote location for processing. One or more dashboards are generated from the data and accessible by the smart device or another computing device.
