ADXL345 is a small, slim, low-power three-axis accelerometer that can measure accelerations up to ±16g with high resolution (13-bit). The digital output data is in 16-bit twos complement format, which can be accessed through SPI (3-wire or 4-wire) or I2c digital interface.
- ADXL345 is very suitable for mobile device applications. It can measure static acceleration of gravity in tilt detection applications, as well as dynamic acceleration caused by motion or impact. It has (4mg/LSB), can measure the inclination of about 0.25°. Use ADXL345 and other digital output accelerometers, without analog-to-digital conversion, which can save system cost and circuit board area.
- ADXL345 is a small and thin ultra-low power 3-axis accelerometer with high resolution (13 bits) and a measurement range of ±16g. The digital output data is in 16-bit two's complement format and can be accessed via SPI (3-wire or 4-wire) or 12c digital interface. ADXL345 is very suitable for mobile device applications. It can measure static acceleration due to gravity in tilt detection applications, as well as dynamic acceleration caused by motion or shock. Its high resolution (3.9mg/LSB) can not measure the change of the inclination angle of L0°. The device provides a variety of specification detection functions. The activity and inactivity detection function compares the acceleration on any axis with the threshold of the user device to detect whether there is movement. The tap detection function can detect single vibration and double vibration in any direction. The free fall detection function can detect whether the device is falling. These functions can be independently mapped to one of the two interrupt output pins. The integrated memory management system uses a 32-level first-in-first-out (FIFO) buffer that can be used to store data, thereby reducing the host processor load and reducing overall system power consumption. Low power consumption mode supports motion-based smart power management , So as to perform threshold sensing and motion acceleration measurement with very low power consumption.
