Abstract
An airflow detecting device includes a pivot rod, a first vane portion hingedly secured to the pivot rod and a second vane portion hingedly secured to the pivot rod. The airflow detecting device further includes a sensor assembly coupled to the first vane portion and the second vane portion. The sensor assembly generates a signal when the one of the first vane portion and the second vane portion is moved relative to the other of the second vane portion and the first vane portion when effected by airflow. The airflow detecting device further includes a control module secured to the pivot rod and coupled to the sensor assembly to receive the signal from the sensor assembly. The control module is configured to determine the direction and the amount of airflow based on the signal from the sensor assembly. Other embodiments of airflow detecting devices are further disclosed.
