MaxBotix high-performance ultrasonic distance sensor – MB1261 XL-MaxSonar-EZL1

The XL-MaxSonar-EZL1 offers lower hardware gain and a smaller, narrower detection range than the MB1260. This makes the XL-MaxSonar-EZL1 a good choice for person detection applications. In addition to detecting small objects, the XL-MaxSonar-EZL1 also detects large targets at the extended range of 1068 cm (420 in).
The sensor is small, but the high acoustic output power combined with continuously variable gain, real-time automatic background calibration, real-time waveform signature analysis and real-time noise cancellation algorithms result in almost noise-free distance measurements.
This applies even in the presence of many different acoustic or electrical noise sources. The XL-MaxSonar EZ sensor line is factory tuned to the sensor's beam patterns and provides long-range detection.
The MB1210 is a version of this sensor with a shorter maximum range.
