AJMRTC GY-291 ADXL345 Digital 3-Axis Accelerometer Gravity Tilt Sensor Module, IIC & SPI Dual Communication Interface, High Resolution Triaxial Acceleration Detector for Arduino DIY Project

AJMRTC GY-291 ADXL345 three-axis acceleration module is a digital gravity and tilt sensor based on ADXL345 accelerometer IC. It can detect static gravity tilt angle and dynamic acceleration, impact and vibration in X, Y, Z three axes simultaneously.

This module features dual IIC and SPI communication options, making it compatible with Arduino, Raspberry Pi and other mainstream MCUs. It supports built-in intelligent detection including single tap, double tap, free fall and activity monitoring. The high 13-bit resolution can capture tiny inclination changes. With low power consumption and compact PCB size, it is perfect for robot posture control, electronic inclinometer, motion alarm, 3D printer resonance test and electronic maker experiments.
