This easy to use sensor is from the Maxbotix company. The LV-MaxSonar-EZ4 offers very short to long-range detection and ranging, in an incredibly small package with ultra low power consumption. The LV-MaxSonar-EZ4 detects objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-inches out to 254-inches with 1-inch resolution. Objects between 0-inches and 6-inches range as 6-inches. The interface output formats included are pulse width output, analog voltage output, and asynchronous serial digital output.

Many Applications require a more narrow beam than the EZ0 and EZ1.  The EZ4 offers the most narrow of the MaxSonar Product line.
