Features of the MB1220, XL-MaxSonar-EZ2, include centimeter resolution, an excellent compromise between sensitivity and side object rejection, short to long distance detection, range information from 20cm to 765cm, a 10Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.
This makes the MB1220 is a great choice for applications that require decreased sensitivity to side objects than the MB1210.
The MB1220 from the XL‑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 MB1220 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.
