Accelerometers
important criteria:
- Interface (simplicity, speed)
- maximum acceleration (or desired range) - usually given in factors of earth's gravitation. (3g means 3 * 10m/s²)
- resolution vs. range (bit depth): increased max. range usually is traded against lower resolution.
- noise (the less the better)
- measurement rate (the higher the better)
Examples
- Cheap and easy to source: Wii Nunchuck - 3 axis, interface: i²c (also works on cheap replacement nunchucks)
- Convenient: Sparkfun ADXL335 breakout board - 3 analog voltage outputs, 3 axis.
- MMA7455 I2C/SPI, 3 axis, tutorial (german)
- ADXL345, I2C/SPI, tested successfully on Arduino, Datasheet code example and library
