A new method based on thin film resistor is proposed to detect dynamic pressure of wind.The film resistance is first converted into air flow rate according to the thermal equilibrium equation

and then the flow rate is converted into dynamic pressure of wind by the Bernoulli equation.Digital filtering is used to remove the collected anomaly data

and Schmitz compensation is used to remove the delay in the sensor detection process

so as to obtain accurate and reliable dynamic pressure of wind data.Experiments show that the wind pressure detection system based on thin film resistor can detect air velocity and wind pressure

and can be widely used in industry

agriculture

wind speed wind pressure measurement and other research fields.
