This is provided to serve as an easy to use set- 
up guide for the LV

MaxSonar

EZ family of 

ultrasonic sensors.  This sensor uses sound to 
measure the distance to nearby objects, and 
then reports the information through one of 
the three sensor outputs. 

MaxBotix Inc., is excited to provide this guide 
which is designed to assist you in using your 
MaxSonar sensor for the first time! 

This quick start guide was created using the 
LV-MaxSonar-EZ1 MB1010 sensor. 

List of Commonly Used Equipment: 

1. Power Supply 
2. Multimeter 
3. Wires 
4. LV

MaxSonar

EZ1 (or one of the other MaxSonar products) 

5. Large flat target – such as a box
