Ping))) Ultrasonic Sensor (#28015)
The Parallax PING))) ultrasonic distance sensor provides
precise, non-contact distance measurements from about 2 cm to 3
m. It is very easy to connect to a microcontroller, requiring
only one I/O pin.
The PING))) sensor works by transmitting an ultrasonic (well
above human hearing range) burst and providing an output pulse
that corresponds to the time required for the burst echo to
return to the sensor. By measuring the echo pulse width the
distance to target can easily be calculated.
More information is available on the website of manufacturer
Parallax.
Examples for Arduino,
BS2 and
Propeller are on
KickStart.

SRF02: Low Cost Ultrasonic Ranger
Lowest cost ultrasonic ranger with both I2C and Serial
interfaces. New AutoTune algorithms intelligently back the
minimum range right up to the transducer ringdown for the very
best performance possible, automatically, in the background, and
with no calibration cycles necessary. Additional new commands
allow for separate burst and ranging control.
More information can be found in the
datasheet SRF02.

SRF04: Ultrasonic Ranger
This high performance ultrasonic range finder is compact and
measures an amazingly wide range from 3cm to 3m. This ranger is
perfect for your robot, or any other projects requiring accurate
ranging information.
The SRF04 is a straight-forward ultrasonic range sensor. The
host microcontroller provides a positive going pulse on the INIT
pin on the sonar module to begin a reading. After the INIT input
pin goes low, the sonar module emits a ping. After the ping, the
ECHO output goes high. It returns low again when the module
receives an echo.
More information can be found in the
datasheet SRF04. Software examples for different microcontrollers can
be found
here.

SRF08: High Performance Range Finder
The SRF08 of Devantech has an incredible range of 3cm to 6m. As
interface I2C is used.
More information can be found in the
datasheet SRF08. Software examples for different microcontrollers can
