HC-SR04 Ultrasonic Arduino Library
HC-SR04 Ultrasonic Arduino Library is specifically for the HC-SR04 ultrasonic sensor. It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy of conversion at different distances for inches and centimeters. Multiple buffers of different lengths can be created for determining standard deviation.

If you are using the arduino-1.0.1 environment, then you must replace "WProgram.h" with "Arduino.h" - works like a charm!
I think, you should set a timout for "pulseIn" in "timing" method. Because if there are multiple sensors, one sensor blocks others, because one sensor waits for an echo for a long time.
Thanks for your effort. This library has been very helpful in my project.
I'm a newbie, so bear with me.
When I try to verify the sketch, it gives me the following error code:
In file included from UltrasonicDemo.cpp:1:
/Users/sabrinawhite/Documents/Arduino/libraries/Ultrasonic/Ultrasonic.h:11:22: error: WProgram.h: No such file or directory
How do I fix this?
