Adxl345 three axis angle tilt sensor gy-2911、 Adxl345 is a small and slim low-power triaxial accelerometer, which can measure acceleration up to ± 16g with high resolution (13 bits).The digital output data is in 16 bit binary complement format and can be accessed through SPI (3-wire or 4-wire) or 12C digital interface.2、 Adxl345 is very suitable for mobile device applications. It can measure the static acceleration of gravity in tilt detection applications, and can also measure the dynamic acceleration caused by motion or impact.It has high resolution (4 mg/lsb) and can measure inclination changes of about 0.25 °. Using digital output accelerometers such as adxl345, there is no need for analog-to-digital conversion, which can save system cost and circuit board area3、 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 binary complement format and can be accessed through SPI (3-wire or 4-wire) or 12C digital interface.Adxl345 is very suitable for mobile device applications. It can measure the static acceleration of gravity in tilt detection applications, and can also measure the dynamic acceleration caused by motion or impact. Its high resolution (3.9mg/lsb) can measure tilt angle changes of less than 1.0 °.The device provides a variety of special detection functions. The active and inactive detection function detects whether there is movement by comparing the acceleration on any axis with the threshold set by the user. The knock detection function can detect single vibration and double vibration actions 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 patent pending integrated memory management system uses a 32 level first in first out (FIFO) buffer,It can be used to store data, so as to reduce the host processor load to a minimum and reduce the overall system power consumption. Low power mode supports intelligent power management based on motion, so that threshold sensing and motion acceleration measurement can be carried out with extremely low power consumption.3mm for adxl345 × 5mm × 1mm, 14 pin small ultra-thin plastic package.
