The Maxbotics XL-MaxSonar family of sonar range finders offers very short- to long-range detection and ranging in an incredibly small package with low power consumption. The XL-MaxSonar detects objects from 0 to 7.65 meters (25 feet) and provides sonar range information beyond 20 cm (8") with a resolution of 1 cm resolution (0.4 in). Objects between 0 and 20 cm range as 20 cm. An efficient transformer uses 0.5 W of power to drive the transducer, yielding high-output acoustic power. This acoustic power, combined with continuously-variable gain, real-time automatic calibration, real-time waveform signature analysis, and real-time noise rejection algorithms, results in virtually noise-free distance readings for most applications, even in the presence of various acoustic or electrical noise sources. The XL-MaxSonar distance sensor is available in five factory-calibrated beam patterns (EZ/AE0-4).
For a less-expensive, lower-resolution, shorter-range version, please consider the LV-MaxSonar-EZ family of distance sensors.
