This easy to use sensor is from the Maxbotix company. The LV-MaxSonar-EZ3 offers very short to long-range detection and ranging, in an incredibly small package with ultra low power consumption. The LV-MaxSonar-EZ3 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 EZ3 offers progressivley narrower beam angle allowing the sensor to match the application.
