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, ...

Today’s computerised engine control systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other important functions. The sensors must provide accurate ...

ANDERSON, S.C. — More stringent emissions requirements have brought about more advanced and highly sensitive oxygen sensors, as well as the placement of more than one O2 sensor in some vehicles. In ...

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 ...
