ADXL345 3-Axis Digital Accelerometer Sensor Module

Accelerometer is used to measure both static acceleration i.e. gravitational and dynamic acceleration i.e. motion or shock. In most of the robotics applications, it is used to measure the tilt of the object. The ADXL345 is a low power, MEMS, three-axis accelerometer module with both SPI and I2C interfaces to communicate with your controller like Arduino, Raspberry Pi, PIC, etc. It also has user-selectable sensitivity and 10-13bit of resolution. This Digital Accelerometer has a voltage regulator on board hence can be connected to both 5V and 3.3V powered controllers. Its high-resolution 4mg/LSB also enables it to measure less than 1° change in the orientation of the object. The ADXL345 Sensor can be used in Robotics applications, measuring vibration in a machine, in the data acquisition system of a vehicle, measuring the motions of a bridge, etc. It can also be used to detect taps on an object.
