PING)))™ Ultrasonic Distance Sensor
The Parallax PING))) ultrasonic distance sensor provides precise, non-contact distance measurements from about 2 cm (0.8 inches) to 3 meters (3.3 yards). It is very easy to connect to BASIC Stamp® or Javelin Stamp microcontrollers, requiring only one I/O pin. The PING))) sensor works by transmitting an ultrasonic (well above human hearing range) burst and [...]

SRF04 Ultrasonic sensor
SRF04 is a non-contact sensors use ultrasonic distance measuring. The working principle of this sensor is a transmitter sends a beam of ultrasonic waves, and then measured the time required until the arrival of the reflection from the object. The duration time is comparable to twice the distance sensor with an object, so that the [...]
