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.
