The Motion Detector 0664 uses ultrasound to measure the distance between the sensor and an object. This Motion Detector has a digital BT connector and can be connected to digital inputs of the VinciLab interface.
 

Range: 0.2 .. 6 to 12 m (depending on an object’s shape, size and surface)
Frequency of ultrasound: 50 kHz
Typical accuracy: ± 1 mm

Includes: a steel rod.
 

Can be used to:
• record motions during walking towards and away from the sensor,
• investigate simple harmonic motion.
• record motions of objects dropped or tossed upward.
