The Accelerometer Bricklet can be used to extend the features of Bricks with the capability to measure acceleration in x-, y- and z-axis. The measured acceleration can be read out in g. With configurable events it is possible to react on changing acceleration without polling.
A continuous acceleration callback can be used to transfer the acceleration data with the full rate of up to 25.6kHz. This high data rate is well suited for predictive maintenance applications.
The Bricklet has an LED that can be turned on trough the API, e.g. to show that a specific acceleration was reached.
