The ADXL345 is a low power 3-axis MEMS accelerometer. This GY-291 module can measure the static acceleration of gravity and dynamic acceleration. Special sensing functions are- Activity/Inactivity monitoring, Single/Double tap detection, Free-fall detection. These functions can be mapped to one of two interrupt output pins. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
Measuring range of ± 2, ± 4, ± 8, ± 16g
SPI and I2C Communication
Ultra Low Power: 40uA in measurement mode, 0.1uA in standby @ 2.5V
