Description: This is the same product as the Maxbotix LV-EZ1. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.

This is the fantastically easy to use sensor from Maxbotix. We are extremely pleased with the size, quality, and ease of use of this little range finder. The serial interface is a bit odd (it’s RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any micro to listen easily enough. The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!

Maxbotix is offering the EZ0, EZ1, EZ2, EZ3, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Please see beam width explanation below.

Control up to 10 sensors with only two pins! Checkout the Maxbotix FAQ listed below.

Customer Comments

  • How sensitive is this sensor? I need it to be capable of receiving input data from a distance of at least 10 ft away.

  • Will people stop watching their favorite tv shows, movies (porn) because someone has on a cross necklace, or cross tattoo etc. Most people don’t even notice it, as long as it has what they want, they don’t care what’s in the background. There are soo many more important things to worry about like finding a cure for cancer, or cure stupidity. :-)

  • RobertC, do you have the ability to disable comments for certain products?

  • Those using this product should be aware that Maxbotix has seen fit to embellish their circuit traces with pro-Christian symbols (visible on the last picture, upside down). Personally, I think it’s totally unethical to force customers to act as unknowing bearers of religious propaganda in this form or any other. We, as engineers and scientists, fight a daily battle against ignorance and prejudice, most of which can trace its roots back to religion and political ideology. We should demand therefore, that the products we use be 100% dogma-free. A circuit board is no place for this type of religious mischief, not now, not ever. Part of having freedom OF religion is having freedom FROM religion.

    • Rich, you must have a guilty conscience and too much spare time. Thanks to the constitution making it clear that we were endowed by our Creator (Yes, TJ used a Capitol C), with certain unalienable rights, Maxbotix is free to design their boards however the hell they want and you are free to not purchase them because of it. Dogma is present from all angles. Please don’t foist your own arrogant dogma on the rest if us.

    • Sparkfun posted a picture of this board’s reverse side. They aren’t trying to stow the symbol away on the board.

    • No more religious comments regarding this product please. It’s been discussed, you aren’t bringing up anything new, it’s all been said before.

    • He’s right, the traces on the back of the board look eerily similar to a Flying Spaghetti Monster.
