The Maxbotics LV-MaxSonar-EZ family of sonar range finders offers very short- to long-range detection and ranging in an incredibly small package with ultra-low power consumption. The LV-MaxSonar-EZ detects objects from 0 to 6.45 meters (21.2 feet) and provides sonar range information beyond 15 cm (6"") with a resolution of 2.5 cm resolution (1 in). Objects between 0 and 15 cm range as 15 cm. The sensor provides three output interfaces, all of which are active simultaneously: digital pulse width output, analog voltage output, and asynchronous serial digital output. The LV-MaxSonar is available in five factory-calibrated beam patterns (EZ0-4).
For a higher-resolution, longer-range version, please consider the XL-MaxSonar-EZ and XL-MaxSonar-AE families of distance sensors.

Selecting the right distance sensor
Since there are 15 members of the XL- and LV-MaxSonar acoustic distance sensor family, we recommend using the Maxbotix sonar range finder selection guide when choosing a acoustic range sensor for your application. There are 5 different beam configurations for the LV-MaxSonar family (EZ0 ? EZ4), each pictured below.
