{"title":"SparkFun Triple Axis Accelerometer Breakout - ADXL345","handle":"sparkfun-triple-axis-accelerometer-breakout-adxl345","url":"/products/sparkfun-triple-axis-accelerometer-breakout-adxl345","description":"\n  This new version adds 2 standoff holes as well as an extra decoupling capacitor. The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +-16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.\n The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0 degrees;.\n Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.\nGet Started with the ADXL345 Guide\nFeatures:\n\n2.0-3.6VDC Supply Voltage\nUltra Low Power: 40uA in measurement mode, 0.1uA in standby@ 2.5V\nTap/Double Tap Detection\nFree-Fall Detection\nSPI and I2C interfaces\n\nDocuments:\n\n Schematic\nEagle Files\nHookup Guide\nDatasheet\n\nExample Code (ATmega328)\nGitHub\n\n\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13632,"title":"Default Title","sku":"SF-SEN-09836","price":42.62,"on_sale":false,"in_stock":true,"available_quantity":111,"option1":"Default Title"}]}
