Topic: Improving accuracy with #2760342 ultrasonic range finder (Read 116 times) previous topic - next topic



I just bought a Radio Shack ultrasonic range finder (3-pins) Model #2760342 and I'm really not impressed with it's accuracy. In my sketch I've converted microseconds to centimeters and then converted to inches. Sometimes it's off by as much as 1/4". This little range finder doesn't measure anything past about 13 feet.

Is there a way to improve the range finder's accuracy in the code... without having to purchase a more expensive sensor?
