A mass air flow sensor is one of the numerous tiny widgets and gewgaws that make up a modern automobile's electronic fuel injection system. In the MAF's case, it tells the car's computer how much air ...

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 ...

I’ve always been fascinated by the many ways that engineers adapt various technologies to create new and better sensors for challenging scenarios, even for basic physical parameters such as ...
