ADXL345 digital triaxial force acceleration tilt module GY-291IIC/SPI transmission sensor

The ADXL345 is a small, slim, low-power triaxial accelerometer that can perform high-resolution (13-bit) measurements of accelerations up to 16 g. The digital output data is in 16-bit binary complement format and can be accessed via SP(3-wire or 4-wire) or 12C digital interface.

The ADXL345 is ideal for mobile device applications. It can measure static gravitational acceleration in tilt detection applications, as well as dynamic acceleration due to motion or shock. It has a high resolution (4mg/LSB) and is capable of measuring about 0.25 Angle changes. The use of digital output acceleration timing such as the ADXL345 eliminates the need for analog-to-digital conversion, which can save system cost and board area.
