Features of the MB1433, HRUSB-MaxSonar-EZ3, include millimeter resolution, a narrow beam as well as excellent side object rejection, short to long distance detection, range information from 300mm to 5000mm, a ~4Hz read rate, and a USB serial output.
The MB1433 has slightly wider beam width than the MB1443 which makes it a good choice for applications where the MB1443 does not have enough sensitivity.
The MB1433 from the HRUSB‑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 MB1433 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.
