Devantech SRF02 Ultrasonic Rangefinder
Lowest cost ultrasonic rangefinder 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.
An I2C interface is available on many popular microcontrollers such as the BASIC Stamp BS2P and may be easily implemented on most PIC Microcontrollers using the PicBasic Pro Compiler from microEngineering Labs.
Examples of using the SRF02 module with a wide range of popular controllers may be found here.
