FULL RESOLUTION: where resolution increases with g range, up to 13-bit resolution at 16 g (maintaining 4 mg/LSB scale factor in all g ranges)MULTIPLE SENSING DETECT: 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. Free fall sensing detects if the device is falling.COMMUNICATION: It uses both I2C and SPI (supports 3-, 4-wire SPI) interface.WIDELY APPLICATIONS: Handsets, instrumentation, Gaming and pointing devices, Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection, Portable gaming.ULTRA LOW POWER: as low as 23 A in measurement mode and 0.1 A in standby mode at VS = 2.5 V (typical).Material:Plastic + Metalcolour:BluePackage Contents:3 X GY-291 ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module3 X 8P Pin HeaderOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
