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 either the
PicBasic or
PicBasic Pro
compiler.
Examples of using the SRF02 module with a wide range
of popular controllers may be found
here.
