SparkFun SEN-00639 Ultrasonic Range Finder – MaxBotix LV-EZ1

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.

    Bought the EZ1 to add ultrasonic distance scanning to a bot already using IR, but having difficulty with less reflective objects. Added to bot, made a simple adjustment to the bot code and away it went, using the analogue output. Added, up and running in
