The HRLV-MaxSonar-EZ sensor line is the fastest way to get precision range-finding into your computer. No microcontroller or adapter required, simply connect any micro B USB cable (not included) into the sensor and install the FTDI drivers to get serial sonar distance data via serial on any computer operating system.
The HR-USB-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a package less than one cubic inch. This sensor line features 1mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-of-sound temperature compensation and optional external speed-of-sound temperature compensation. This ultrasonic sensor detects objects from 1mm to 5meters, senses range to objects from 30cm to 5meters, with large objects closer than 30cm typically reported as 30cm.
