ADXL335 Analog Accelerometer
Now available from PMD Way is this easy to use ADXL335 Analog Accelerometer.
The ADXL335 MEMS accelerometer from Analog Devices can detect joint movement as well as inclination and vibration, and outputs a 0V to 3V analog signal on each of the X, Y, and Z axis.
You will need to convert 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.
Board is compatible with 5V and 3.3V board; inline header pins are included but not soldered to the board.
