- power supply - 5V at only 15mA, this is reduced to 3mA in standby mode.
- distance - With a 40khz ping the SRF10 measures from 3cm to 6m.
- fully calculated result - you don't have to worry about timing a response pulse or scaling the result.
- Size - The SRF10 measures only 32mm x 15mm x 10mm.


The communication with the ultrasonic rangefinder SRF10 takes place via the I2C bus. This is available for common controllers such as OOPic and Stamp BS2p as well as for a variety of microcontrollers. For the programmer, the SRF10 behaves like the ubiquitous Eeprom's of the 24xx series, except that the I2C address is different. The default address of the SRF10 is 0xE0. It can be changed by the user to any of the 16 addresses E0, E2, E4, E6, E8, EA, EC, EE, F0, F2, F4, F6, F8, FA, FC or FE, so up to 16 sonar devices can be used.

The connections to the SRF10 are identical to the SRF08. The pin "Do Not Connect" should not be connected. It is actually the CPU MCLR line and is only used once in our workshop to program the PIC16F87 on-board after assembly, and has an internal pull-up resistor. The SCL and SDA lines should each have a pull-up resistor up to +5V somewhere on the I2C bus. They require only a pair of resistors, not a pair for each module. They are normally located at the bus master and not at the slaves. The SRF10 is always a slave - never a bus master. If you need them, I recommend 1.8k resistors. Some modules like the OOPic already have pull-up resistors and you don't need to add any more.
