Features of the MB1020, LV-MaxSonar-EZ2, include one-inch resolution, an excellent compromise between sensitivity and side object rejection, range information from 6 inches to 254 inches, a 20Hz read rate, and various output options: pulse-width, analog voltage, and RS232 serial.
This makes the MB1020 is a great choice for applications that require decreased sensitivity to side objects than the MB1010.
The MB1020 from the LV‑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 MB1020 learns the ringdown pattern when commanded to start ranging. This helps the sensor to learn the environment and can help the sensor ignore obstacles that are present at power-up.
