MaxBotix MB1033 HRLV-MaxSonar-EZ3 Ultrasonic Sensor

In addition, the MB1033 offers virtually noise free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
