HRUSB-MaxSonar-EZ1 MB1413 Ultrasonic Distance Sensor

The MB1413 HRUSB-MaxSonar-EZ1 has millimeter resolution and a ~4Hz read rate, features a great blend of sensitivity as well as side object rejection, and provides short to long distance detection and range information from 300mm to 5000m. The sensor utilizes a USB micro-B connector for sensor interfacing.
This makes the MB1413 a good low-cost starting place for a customer not sure of which HRUSB-MaxSonar-EZ sensor to use.
The MB1413 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 MB1413 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.
