SRF08 - I2C range finder
Power - 5v at only 15mA, this reduces to 3mA in standby condition
Communication - Standard I2C Bus.
Distance - Using a 40khz ping the SRF08 measures from 3cm upto 6m. The result can be scaled by the SRF08 to uS, cm or inches.
Multiple echo detection - Upto 17 responses can be detected, these are placed in an array of registers sorted in order of distance.
Fully calculated result - No need to worry about timing a response pulse or scaling the result.
Light Sensor - Front Facing light sensor is read with ranging command and light intensity is read and placed in a convenient register
Size - The SRF08 measures just 43mm x 20mm x 17mm.
