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:

    “It was undoubtedly the feeling of exile—that sensation of a void within which never left us, that irrational longing to hark back to the past or else to speed up the march of time, and those keen shafts of memory that stung like fire.”
    —Albert Camus (1913–1960)
