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.
