The MaxSonar EZ1 provides very short to long-range detection and ranging, in an incredibly small package. It can detect objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-inches out to 254-inches with 1-inch resolution. (Objects from 0 inches to 6-inches range as 6-inches.) The interface output formats included are pulse width output (PWM), analog voltage output (Vcc/512 volts per inch), and serial digital output (9600 baud). A good sensor for when a Sharp IR distance sensor won't cut it.

Step 1: Are you a pro? Go straight to the datasheet...

If youre a pro cut straight to the data sheet- if not, here's a quick start guide on using the Maxbotix sonar sensor&
<p>Nice write up. The diagram is a bit wrong however. The ground from the sensor is connected to the power on your breadboard diagram. Black wire from sensor should connect to black horizontal row on breadboard, not the power horizontal row.</p>
I need help!!! <br> <br>I am working on a project for school and I need it to work to graduate. My project is to integrate a proximity/ sonar sensor onto an RC car to make it stop if it gets within a certain distance from an obstacle. before I can even begin to worry about integrating the sensor on the car I need to get it to work with the arduino uno. I am having difficult getting the program to work for the sonar sensor. I know that the original schematic and code was designed to work with an arduino diecimila, but all I could find was an uno. what can I do to make this work? I am using the maxbotix sonar sensor and the piezo buzzer used in the quick start guide. Please help me out
Nice tutorial. <br /> <br />I'm doing a similar project and I'd like to document it but I'm unable to locate the fritzing part for the MaxBotix sensor. Did you create this one on your own?
is their any way you can make a trigger with a tela photo lens. but remeber the light that triggers it is emeral and its about 25 feet away if you could help out post back.
What advantages/disadvantages do the other pin outs offer?<br /><br /><br />

Nice diagram. What program did you use to generate it?<br />

like that green circle thing on a submarine that shows where things are?
so what does this actually do?
its SONAR (sound navigation and ranging) it is like what bats have to see because they are sort of blind.... a,k.a Uber- Hearing
