SUMMARY
This discussion focuses on creating an air flow meter using a heating element sourced from an iron. The proposed method involves inserting the heating element into a duct and measuring the current changes as air flows over it, which affects its temperature and resistance. Concerns were raised regarding the accuracy of this method, suggesting the need for additional temperature measurements upstream and downstream. The participant also plans to convert the current readings to voltage for use with a microcontroller.
