The XL‑MaxSonar‑EZ1 offers a lower hardware gain and a smaller, narrower detection zone than the MB1200. This makes the XL-MaxSonar-EZ1 a great choice for people detection applications.
The sensor is small in size, yet the high output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and real-time noise rejection algorithms results in virtually noise free distance readings for most users. This holds true even in the presence of many of the various acoustic or electrical noise sources. The XL‑MaxSonar‑EZ sensor line is factory calibrated to match the sensor beam patterns and provides a long range detection zone.
The MB1261 is an extra-long range version of this sensor.
