SRF04 - Ultrasonic Range Finder
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 URS 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.
Check out a BS2 example program here.
Note, due to a timing bug with the BASIC Stamp 2, you must use pin0 to measure the echo pulse!
