The air flow detector circuit diagram is a schematic diagram. You understand that the air flow in the detector schematics, we give you about the air flow detector is an important component LM335.LM335's description:
The LM135 series are precision, easily-calibrated, integrated circuit temperature sensors. Operating as a 2-terminal zener, the  LM135 has a breakdown voltage directly proportional to absolute temperature at 10 mV / ° K. With less than 1W dynamic impedance the device operates over a current range of 400 μA to 5 mA with virtually no change in performance.When calibrated at 25 ° C the LM135 has typically less than 1 ° C error over a 100 ° C temperature range. Unlike other sensors the LM135 has a linear output.Applications for the LM135 include almost any type of temperature sensing over a -55 ° C to 150 ° C temperature range. The low impedance and linear output make interfacing to readout or control circuitry especially easy.The LM135 operates over a -55 ° C to 150 ° C temperature range while the LM235 operates over a -40 ° C to 125 ° C temperature range. The LM335 operates from -40 ° C to 100 ° C. The LM135/LM235/LM335 are available packaged in hermetic TO-46 transistor packages while the LM335 is also available in plastic TO-92 packages.
