Airflow Sensor and Airflow Detecting Module

摘要

An airflow sensor is disclosed to overcome the problem of having an undetectable wind speed range. The airflow sensor may include a frame and an impeller. The frame includes a rotation detector. The impeller is rotatably coupled with the frame and includes a plurality of blades and a rotating member. The rotation detector generates a detection signal according to a rotational cycle of the rotating member. Moreover, an airflow detecting module is further provided to overcome said problem.
