Devantech SRF10 Ultrasonic Rangefinder
The world’s smallest ultrasonic rangefinder for accurately measuring distances between 3cm and 6m.
Communication with the SRF10 module is via the I2C bus. To the programmer the SRF10 behaves in the same way as a 24xx series EEPROM, except that the I2C address is different. The address of the SRF10 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 the PicBasic Pro Compiler from microEngineering Labs.
Examples of using the SRF10 module with a wide range of popular controllers may be found here.
