Accellerometers and traction control

As my friend Fabio suggested, I should include some accellerator sensors to better perform the traction control.

The task should not so difficult since there are many accellerometers on the market even for low prices. In particular, I think is better to look at those having a digital interface (i.e. IIC2 or SPI bus) instead of those having pure analogue output. Looking around I've found many but all have tiny pacheages so are really difficult to be soldered! Thanks to FuturaElettronica we can get a soldered 3-axis accellerometer for only 13€: link.

How it works?

The digital accellerometers are MEMS componenet having one floating part inside that goes to change 3 capacitances (each capacitor is perpendicular to each other: one in X direction, one in Y and one in Z), the capacitance variation are then converted to digital signals by appropriate circuitry integrated on the same die. Typically they could measure +/-1.5g or +/-6g, but for the byke the +/-2g should be enough, so the MMA7455LT could be ok.
