This is a three-axis accelerometer for the LilyPad system. Based on the ADXL335 accelerometer from Analog Devices, the LilyPad Accelerometer can detect joint movement as well as inclination and vibration.
The ADXL335 puts out a 0V to 3V analog signal on each of the X, Y, and Z axes. You will need to relate this analog voltage to a gravity amount and use trigonometry to calculate a true 'angle'. If you are not looking for tilt, it is very easy to use this sensor for basic motion sensing.
LilyPad Overview LilyPad is a wearable e-textile technology developed by Leah Buechley. Each LilyPad is designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. Most are even washable — just remember to remove any batteries first.
See our LilyPad category to find more LilyPad components and conductive thread you can use to sew a circuit into clothing.
