Abstract

An airflow characterization system includes a first airflow sensor subsystem positioned at a first location on an airflow characterization board base and a second airflow sensor subsystem positioned at a second location on the airflow characterization board base that is different than the first location. An airflow characterization controller is coupled to the first airflow sensor subsystem and the second airflow sensor subsystem. When the airflow characterization board is positioned in a circuit board slot, the airflow characterization controller receives a first airflow signal from the first airflow sensor subsystem during a first time period and receives a second airflow signal from the second airflow sensor subsystem during the first time period. The airflow characterization controller determines a circuit board slot airflow characterization for the circuit board slot based on the first airflow signal and the second airflow signal.
