MB1240 Ultrasonic Sonar Module

APM Pixhawk XL-MaxSonar EZ4 Ultrasonic Range Finder MB1240

The XL‑MaxSonar‑EZ4 has the highest noise tolerance and narrowest beam of any of our indoor sensors. The sensor is designed and calibrated to provide reliable range information to large targets even in environments with strong acoustic or electrical noise sources.

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 XL-MaxSonar-EZ4 performance to large targets is only beaten by the MB7052.
