Peace of mind dryer

A method for detecting a variation in airflow through a vent of a dryer, the method comprising:

• receiving sensor data from at least one sensor in an air conduit of a clothes dryer;
• determining an estimated airflow based on the sensor data;
• comparing the estimated airflow to a predetermined expected airflow;
• and
• adjusting the estimated airflow in response to the estimated airflow not being within a predefined margin of the predetermined expected airflow.

A vent system for a dryer, comprising:

• an exhaust air conduit configured to provide an airstream to a dryer;
• a sensor within the conduit and configured to measure the airstream, wherein the sensor is a whistle sensor configured to detect sounds within the conduit outside of human audible range to provide a continuous airflow reading based on the detected sounds;
• and
• a controller configured to receive sensor data from the whistle sensor indicative of airflow of the airstream.
