Abstract
A digital air flow detector that includes a pair of thermistors contained in a probe. When installed, an external thermistor is positioned in an air stream, while an insulated thermistor is not. When air is flowing, the air stream will change the temperature of the first thermistor more than the second thermistor. A microcontroller unit measures the temperature difference between the two thermistors and determines whether air is flowing based on the difference. The digital air flow detector outputs an accurate binary indication of whether the air is flowing or not flowing. An air flow detector includes a probe assembly and a printed circuit board assembly coupled to the probe assembly.
