PING))) ultrasonic range sensor kit

The PING))) ultrasonic sensor is perfect for applications that require you to perform distance measurements between moving or stationary objects. The sensor measures distance using sonar: an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return. Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target. When coupled with the servomotor in this kit, the PING))) sensor can make a 180° scan of its environment and an obstacle map created. Together they're great for autonomous navigation.

Note

PING))) is ideal for use with Raspberry Pi and Arduino based robot projects.
