com Devantech SRF04 Ultrasonic Range Finder (#28015) The Devantech SRF04 ultrasonic range finder provides precise, non-contact distance measurements from about 3 cm (1.
2 inches) to 3 meters (3.
3 yards).
It is very easy to connect to BASIC Stamps or the Javelin, requiring only two I/O pins.
1 The SRF04 library makes this device very simple to use and is an ideal component for robotics applications.
The SRF04 works by transmitting an ultrasonic (well above human hearing range) pulse and measuring the time it takes to "hear" the pulse echo.
Output from the SRF04 is in the form of a variable-width pulse that corresponds to the distance to the target.
The SRF04 is designed and manufactured by Devantech, who provides additional technical resources for the device.
