SRF02 Ultrasonic Range Finder - Part No: 3801-006
Best in class performance!

Lowest cost ultrasonic ranger with both I2C and Serial interfaces. New AutoTune algorithms intelligently back the minimum range right up to the transducer ringdown for the very best performance possible, automatically, in the background, and with no calibration cycles necessary. Additional new commands allow for separate burst and ranging control.

Easy connection to USB host with the USBI2C module. Self powered from the USB bus.
