I recently got a Maxbotix LV-EZ4 Ultrasonic Range Finder to try understand how to use it with my little Arduino.

It works better outdoors then the IR sensor, but the only thing I could notice is that it doen’t detects very well some thick carpets. Besides that, it’s a great sensor. From the datasheet we can read that it sonar range information from 6-inches out to 254-inches (15.24 cm – 6.452m).
