Abstract: An airflow measurement system includes a plurality of communication modules and an information processing apparatus. The communication module includes an airflow sensor, and a body portion including a communication unit configured to acquire data output from the airflow sensor and transmit the data to outside by wireless communication. The information processing apparatus includes a data collection unit configured to collect the data output from the airflow sensor of the plurality of communication modules, and an output unit configured to output the collected data.

Abstract: A fluid sensing apparatus includes a fluid sensor configured to detect a temperature distribution on a detection surface caused by heating, and output a signal value corresponding to a flow of a fluid; a falling time counting unit configured to count a falling time of the signal value after stopping the heating; and a failure determining unit configured to perform failure determination based on the falling time.
