Description
Set ini terdiri dari :
1 Unit SRF10 Ultrasonic Sensor
1 Unit Mounting backet untuk SRF10
Power – 5v at only 15mA, this reduces to 3mA in standby condition
Communication – Standard I2C Bus.
Distance – Using a 40khz ping the SRF10 measures from 3cm upto 6m. The result can be scaled by the SRF10 to uS, cm or inches.
Fully calculated result – No need to worry about timing a response pulse or scaling the result.
Ultra small size – The SRF10 measures just 32mm x 15mm x 10mm.

This small sonar ranger from Devantech offers an amazing wide range from 3cm to 6m. The SRF10 is interfaced using the IIC bus.
Communication with the SRF10 ultrasonic rangefinder is via the I2C bus. This is available on popular controllers such as the OOPic and Stamp BS2p, as well as a wide variety of micro-controllers. To the programmer the SRF10 behaves in the same way as the ubiquitous 24xx series eeprom’s, except that the I2C address is different. The default shipped address of the SRF10 is 0xE0. It can be changed by the user to any of 16 addresses E0, E2, E4, E6, E8, EA, EC, EE, F0, F2, F4, F6, F8, FA, FC or FE, therefore up to 16 sonar’s can be used.
