GY-291 ADXL345 digital three-axis acceleration of gravity tilt module IIC / SPI

Description : GY-291, ADXL345 digital, three axis gravity acceleration, slope module, IIC/SPI transmission Model: GY-291 Using chips: ADXL345 Power supply: 3-5v Communication mode: IIC/SPI communication protocol Measuring range: + 2G + 16g Provide schematics, related data manuals and reference documents Provide 51, AVR, Arduino SCM test code A large number of stock, you can directly take, the amount of big price excellent! 3 axis, + 2g/ + 4g/ + 8g/ + 16g Digital acceleration module Summary ADXL345 is a compact and slim low power three axis accelerometer, on high Acceleration of + 16 g is performed with high resolution (13 bit) measurements. Digital output It is a 16 bit binary complement format, Access via SPI (3 line or 4 line) or I2C digital interface. ADXL345 is ideal for mobile device applications. It can be used in tilt detection applications Measure the static gravity acceleration, and also measure the dynamic addition caused by motion or impact Speed. It has a high resolution (4 mg/LSB) and is capable of measuring about 0.25 degrees of inclination Angular variation. The use of ADXL345 and other digital output acceleration timing, without the need to proceed Analog to digital conversion, which can save system cost and circuit board area. Besides, ADXL345 is a small, thin, ultra low power, 3 axis accelerometer with resolution High (13 bit), measuring range of + 16g. The digital output data is 16 bit binary The complement format can be accessed via SPI (3 line or 4 line) or I2C digital interface. ADXL345 is ideal for mobile device applications. It can be applied in tilt detection Measure the static gravity acceleration, and also measure the movements caused by motion or shock State acceleration. Its high resolution (3.9mg/LSB) can measure less than 1 degrees Tilt angle change. The device offers a variety of special detection functions. Active and inactive detection function Compare the acceleration on the arbitrary axis with the threshold set by the user to check if there is any movement Occur. The knock detection function can detect single vibration and double vibration in any direction For. The free fall detection function detects whether the device is dropping. These ones here The function can be mapped independently to one of the two interrupt output pins. Shen Shen The patented integrated memory management system employs a 32 stage FIFO (FIFO) buffers can be used to store data and thereby load host processors Minimizes and reduces overall system power dissipation. Low power mode supports motion based smart power management, resulting in extremely low power Power consumption is measured by threshold sensing and motion acceleration measurements. The ADXL345 uses 3 mm x 5 mm x 1 mm, 14 lead Mini slim plastic Encapsulation. Features: The device offers a variety of special detection features. Active and Inactive Detection Detects the presence or absence of motion by comparing the acceleration on any axis with a user-set threshold. Percussion detection function can detect any direction of single vibration and double vibration action. Free fall detection function can detect whether the device is falling. These functions can be independently mapped to one of two interrupt output pins. The patented integrated memory management system uses a 32-level first-in-first-out (FIFO) buffer to store data, minimizing host processor load and reducing overall system power consumption. Specification: Main chip: ADXL345. Model: GY-291 Power supply :3-5v. Means of communication: the iic / spi communication protocol. Measuring range: ±2g /±16g
