The MaxSonar®-EZ1™ offers very short to long-range detection and ranging, in an incredibly small package, with ultra low power consumption. The MaxSonar®-EZ1™ detects objects from 0-inches, even objects pressing against the front sensor face, to 254-inches (6.45 meters), and provides sonar range information from 6-inches to 254 inches, with 1-inch resolution. Objects between 0-inches and 6-inches range as 6-inches.
Traditional dual-sensor piezoelectric ultrasonic range-finders have many subtle peculiarities. These include the inability to detect very close objects, a central up-close blind spot between the transducers, and very wide-angle beams (some more than 90 degrees!). In addition, if a piezoelectric sensor has a narrow beam, it will, in general, have much shorter detection zones, especially for small objects.
The MaxSonar®-EZ1™ overcomes these problems and more by utilizing a single 42KHz ultrasonic transducer coupled with a continuously variable high gain amplifier. The MaxSonar®-EZ1™ is half the size of competing sensors, while the 2mA nominal current draw is the lowest of any range sensor.
The MaxSonar®-EZ1™ is very easy to use. It has holes for easy mounting, and provides the range directly, using three user interfaces. The pulse width output is similar to other low cost ultrasonic range finders. The analog voltage output provides 10mV per inch output and always holds the latest range reading. In addition, after each range event the digital output sends asynchronous serial data in an RS232 format, except voltages are 0-5V.
