ULTRASONIC RANGE FINDER - LV-MAXSONAR-EZ1, SPARKFUN, SEN-00639

This is the fantastically easy to use sensor from Maxbotix. At Sparkfun 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.
