Sonar Phidget
For applications of spatial awareness and motion sensing, this handy Sonar Phidget is unmatched. It emits pulses of ultrasonic vibration at a rate of up to 10 pulses per second. After each pulse, it “listens” for ultrasonic waves that have reflected off of objects up to 10m away and sends them to your computer via the sensor update event. The Sonar Phidget can detect up to 8 reflections in a single pulse, and will report the approximate distance and strength of each reflected wave. The DST1200 connects to a port on a VINT Hub. See the “Comaptible Products” tab for a list of hubs.
Useful in Robotics
The Sonar Phidget can be used as an ultrasonic range finder. The distanceChange event automatically returns the distance of the strongest reflection whenever new data comes in. This mode is commonly used for obstacle detection in robotics projects.
