This module - and the associated library - allow you to connect up to 16 HC-SR04 ultrasonic range sensors to an Arduino using the I2C bus and one hardware interrupt pin.
I wanted more sensors on my robot to help it navigate. I'm too cheap to buy a mega board with enough pins or smarter sensors that need less pins. My initial board supported 8 sensors which I placed around the robot, two on each of the four sides to allow the measurement of the alignment to the maze wall without moving. This left blind spots at the corners - which called for more sensors. As they make a 16 pin version of the chip, I figured: why not?
The library handles all the timing, and the hardware interrupts provide surprisingly high accuracy. Each unit is individually tested using an Arduino test-bed and ships with separate pin headers. 12 sensors can be supported with 8 four-pin wires in combination with my Trimount brackets by plugging them in at right angles.
I am stocking some of the sensors and cables too, so you can get them at the same time. These are batch tested to verify that they are not the type with the echo-lock problem. See this thread on the Arduino forum

Robot pack includes the base pack plus:
A reviewer noted that the wiring for the trimount brackets is poorly documented. This is true! I will try to do better. In the mean time - the video below has the best available explanation at around 3:55
