We don’t have much personal experience with DOF hardware, but this Arduino library which reads and compensates for three-axis magnetometer and accelerometer data looks very impressive. It sho… ...

So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 (pressure, altitude, temperature) and MPU6050 (accelerometer and gyroscope).

February 10, 2012 [Boris Landoni] put together a guide to using an inexpensive 3-axis accelerometer with Arduino. The chip that he chose for the exercise is an MMA7455L made by Freescale.

The AXO301 and AXO305 MEMS accelerometers are sampling now. Also available is an AXO Arduino-based evaluation kit that provides built-in testing functions, such as output reading and recording, ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...
