SENS-ADXL346 Triaxial Acceleration Sensor Module Accelerometer I2C SPI IIC ADXL346

This is a small, thin, ultra low power, 3 axis accelerometer with high resolution (13bit) measurement up to 16 g. Digital output data format for 16 bit binary, and can be through a SPI (3 - or 4 wire) or I2C digital interface. (Replacement  ADXL345)
Description:
The ADXL346 is well suited for mobile device applications. It measures the use of static gravity acceleration in tilt sensing applications, as well as the acceleration of dynamic acceleration motion or vibration caused by its high resolution (4mg / LSB) can be measured tilt change is less than 1 degrees of inclination.

Some special induction functions are provided. Comparisons are made for the presence or absence of motion acceleration such as the presence or absence of remote sensing probe activities and the g values for the user to compare with any axial acceleration. Click sensing to detect in single, double click any direction. Free fall sensor, if the device is falling down.

ADXL346 built in the directional detection capability of concurrent four, six position detection and the user can use the selected interrupt notification controller. These features can be mapped individually to the following two interrupt output pins. An integrated, patent pending memory management system, 32 first in first out (FIFO) buffer, which can be used to store data, to minimize the host processor activity, reduce the overall system power consumption. Low power mode enables intelligent motion power management with threshold detection and active acceleration measurements at very low power consumption.
