SRF08 Ultrasonic Rangefinder
|
|
|
A high performance ultrasonic rangefinder for accurately
measuring distances between 3cm and 6m.
Communication with the SRF08 module is via the I2C bus.
To the programmer the SRF08 behaves in the same way as a
24xx series EEPROM, except that the I2C address is different.
The address of the SRF08 can be changed by the user to any
of 16 addresses allowing up to 16 rangefinders to be used
simultaneously on the same I2C bus.
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 SRF08 module with a wide range
of popular controllers may be found
here.
