| Abstract: | The advantages of hot-film air flow sensor are small size, high sensitivity, high safely and reliability, short response time, which has a hybrid electric circuit structure. The core of external circuit is STM8L151. The single chip controls the temperature of heater efficiently and filters and amplifies the signals which on the hot-film. The computer interface made on LabVIEW, make the calibration fast and automatically. |
