Named after its french creator, Henri Pitot, a pitot tube is a device used to approximate the speed of vehicles traveling through air and other fluids. Pitot tubes, also called pitot-static tubes and Prandtl tubes, are primarily used as airspeed indicators on drones, airplanes, and other rotorcraft. Pitot tubes use basic fluid dynamics and the Bernoulli equation to approximate airspeed, or relative velocity, of a moving vehicle/flying object. The pitot tube here can be combined with our XGMP3v3 Differential Pressure Sensor to measure pressure, which is then converted to a digital signal using an Arduino board or other analog-to-digital converter (ADC).
