Speed Sensor

Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. They include:

  • Wheel speed sensors
  • Speedometers
  • Pitometer logs
  • Pitot tubes
  • Airspeed indicators
  • Piezo sensors (e.g. in a road surface)
  • LIDAR
  • Doppler radar
  • ANPR (where vehicles are timed over a fixed distance)
  • Laser surface velocimeters for moving surfaces

Famous quotes containing the word speed:

    “No speed of wind or water rushing by
    But you have speed far greater.”
    —Robert Frost (1874–1963)
