It does away with clunky mechanical floats, and easily interfaces with electronic control systems.

This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid.

With a sensor aiming the floor, not only you can detect lines, but often, floor with low reflection and dark color can be used to distinguish different areas. For example, a kitchen with a dark floor and a living room with a light or white floor, given this information to your robot you can keep it enclosed to a specific area or even let the robot know the area to change it's behavior.

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g.

Its high resolution (4 mg\/LSB) enables measurement of inclination changes less than 1.0°.Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.

The self heating (15mW at 5V, or 8mW at 3.3V) will change the temperature of the sensor by 3 degrees C or so. (The amount of self heating is also slightly dependent upon user mounting).
