An accelerometer board based on the 3 axis ADXL335 IC from Analog Devices. It comes with an onboard voltage regualator and hence works on a wide range of input voltage from 5V to 15V. The sensor can measure accelerations range of +/-3g.The sensor can be used for tilt sensing,motion sensing, vibration monitoring, Real Time Orientation detection, Freefall detection, etc. The sensor can be interface through a simple analog interface. The voltage on the three pins X, Y and Z is always corresponding to the orientation of the sensor. The sensor has one mounting hole to fix the accelerometer onto a support. Board comes fully assembled and tested with external components assembled.
