MaxBotix MB1033 HRLV-MaxSonar-EZ3 Ultrasonic Sensor


The MB1033 has slightly wider beam width than the MB1043 which makes it a good choice for applications where the MB1043 does not have enough sensitivity. The MB1033 from the HRLV‑MaxSonar‑EZ line of sensors is a very small, less than one cubic inch, ultrasonic sensor component module. This sensor comes with mounting holes provided on the circuit board for easy installation in nearly all applications.

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.
