Pb free/RoHS compliant

Several special sensing functions are provided:
Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds.
Tap sensing detects single and double taps in any direction.
Freefall sensing detects if the device is falling.
These functions can be ped individually to either of two interrupt output pins.

Pin definition:
5V: 5V power supply
3V3: 3.3V power supply
GND: ground
Vs: supply voltage
CS: chip select
SCL: I2C serial clock line/SPI clock terminal
SDA: Serial Data (I2C) / Serial Data In (SPI 4-wire) / Serial Data In and Out (SPI 3-wire)
S DO: Serial Data Output (SPI 4-wire) / Alternate 12C Address Select (I2C)
INT 2: Interrupt 2 pin

Instructions for use:
Note that the address of the module in 12C mode is determined by the S DO pin

Package Included:
5 x ADXL345 Gravity Sensor Acceleration Module

• ADXL345, it's a low cost cap-based accelerometer sensor, 3-axis accelerometer with high resolution (13-bit), high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°..
• Digital output data is formatted as 16-bit twos complement, supports I2C/SPI, low power, compact accelerometer..
• The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock..
• Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds..
• individually to either of two interrupt output pins..
