The LilyPad Accelerometer is a three-axis accelerometer based on the Analog Devices ADXL335, designed for the LilyPad wearable e-textile system. It detects joint movement, inclination, and vibration, outputting 0–3 V analogue signals on the X, Y, and Z axes.

The board features large sewable pads and a thin 0.8 mm PCB for comfortable integration into clothing and wearable projects. For tilt angle calculation, the analogue voltage needs to be converted to a gravity value using trigonometry; for basic motion sensing, the raw analogue output can be used directly.
