This paper describes a ventilation control system
designed using off-the-shelf components. The system has outputs
for two fans, inputs for two wind meters, a power switch, a
touchscreen monitor, and three warning indicators. The system
measures air flow within ± 1 f/m using the WeatherFlow wind
meters. The microprocessor used to control the system offers
manual or automated control. The automated system maintains
air flow within ± 24 f/m and can re-establish air flow within 160
seconds of partial air flow blockage
