LV-MaxSonar-EZ4 MB1040 Ultrasonic Distance Sensor

The MB1040 LV-MaxSonar-EZ4 sensor features one-inch resolution and a 20Hz read rate, provides the narrowest beam width of any sensor in the LV-MaxSonar-EZ sensor line and range information from 6 inches to 254 inches, and includes various output options: pulse-width, analog voltage, and RS232 serial.
The MB1040 is a great choice for applications where only larger objects need to be detected.
The MB1040 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 MB1040 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.
