Description
ADXL345 is a small, thin low-power three-axis accelerometer may be high nfor a high resolution (13) of ± 16 g measured acceleration. The digital output ndata is 16-bit two’s complement format, n nVia SPI (3 or 4-wire) , or by a digital interface to the I2C. nADXL345 is very suitable for mobile device applications. It can tilt detection applications nmeasuring static acceleration of gravity, can also be measured dynamically add or movement due to impact nspeed. It has a high resolution (4 mg / LSB), capable of measuring about 0.25 ° of tilt nangle change. Using digital output accelerometers such as ADXL345, without nanalog-to-digital conversion, which can save system cost and circuit board area. In addition, n nThe ADXL345 is a small and thin ultra-low power 3-axis accelerometer with nhigh resolution (13 bits) and a measurement range of ± 16g. The digital output data is in 16-bit two’s ncomplement format and can be accessed via SPI (3-wire or 4-wire) or I2C digital interface. ADXL345 is very suitable for mobile device applications. It can tilt detection application nmeasuring static acceleration of gravity may also be measured up movement due to impact or ndynamic acceleration. With its high resolution (3.9mg / LSB), it can measure nchanges in tilt angle less than 1.0 ° . The device provides a variety of special detection functions. Detection of active and inactive through nthreshold by comparing the acceleration on any axis to detect the presence or absence of user setting operation noccurs automatically. 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 nfunctions can be independently mapped to one
