| Anemometer is an important instrument for measuring wind speed.Aiming at those problems such as large volume,inconvenient carrying,and easy to damage in the harsh environment.Thermistor is designed based on wireless anemometer.The anemometer with STC12C5620AD micro-controller and E32-TTL-100 wireless data transmission module as the core.Making use of heat sensitive type of FS5 wind speed sensor to overcome the traditional thermal anemometer probe "fragile" and not easy to clean up the shortcomings.At the same time,there are advantages with large range,high sensitivity,using large temperature range,long life of battery.Through low speed wind tunnel to calibrate,using the least square fitting.In addition,the equation is in accord with the exponential distribution,and the multiple regression coefficients are 0.996 and 0.997 to fit the needs of practical. |
