Create awareness of your surroundings. Ultrasonically senses distances of objects, persons, walls from 0.152 to 6.45 m (0.500 to 21.2 ft.). Is invisible to the audience. Completely silent to the human ear, hence it is suitable for sound installations. Check the FarReach if you need a range of upto 12 m (39 ft.).
Application examples
- Use for distance measurement relative to a wall or presence detection of objects and persons (it cannot detect the number of people present).
- Combine with a TapTiled floor, some MoveOn and/or ReachClose sensors and make sure every move of your visitor has an effect. Perhaps the TouchStripOn is useful for additional coverage on walls. The Flash + SeeLaser combo allows you to implement break-beams that could indicate borders or thresholds.

- upon power-up, the sensor performs a distance calibration, so if anything is closer than 35 cm (14 inch) it can cause close objects to be ignored
- multiple Advance-645 sensors can be placed adjacently where the spacing is determined by the maximum distance to be measured at which distance the ultrasound emission cones should not overlap
- any indirect echoes of the ultrasonic pulse (eg. from the sidewalls in a narrow corridor) may generate incorrect sensor output values
