This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...

Among the many methods available for air flow detection, self-heated thermal flow sensors are simple, cheap, rugged, and sensitive. They rely on the relationship between airspeed (AF) and thermal ...

Last month, we kicked this series off by showing you how to save some money by diagnosing a bad MAP sensor rather than just chucking cash at new parts that may or may not fix a specific problem. This ...
