Alinan 4pcs GY-291 ADXL345 3-Axis Digital Three-axis Acceleration of Gravity Tilt Module for Arduino IIC/SPI Transmission

Features: The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. Low-power mode supports motion-based intelligent power management for threshold sensing and motion acceleration measurement with very low power consumption. 3-Axis digital acceleration high resolution (4 mg / LSB), capable of measuring about 1.0 ° of inclination angle change, use ADXL345 digital output acceleration timing, etc, without the need for analog to digital conversion, reducing system cost and board space. Specifications: Main chip: ADXL345 Means of communication: the IIC / SPI communication protocol. Supply voltage range: 3V to 5V Digital-output triple- axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g and integrated 16-bit ADCs Accelerometer normal operating current: 450µA Ultralow power: as low as 23 μA in measurement mode and 0.1 μA in standby mode at VS = 2.5 V (typical) Sleep mode current: 8µA Communication: SPI (3- and 4-wire) and I2C digital interfaces User-programmable interrupts Wake-on-motion interrupt for low power operation of applications processor MULTIPLE SENSING DETECT: Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free fall sensing detects if the device is falling. Package inlcuded: 4 X GY-291 ADXL345 3-axis digital acceleration module 4 X 8P pin header

Product Features

• The ADXL345 is a small, thin, ultra-low power 3-axis accelerometer Up to 16 g accelerometer with high resolution (13) measurement. Digital outputs according to a 16-bit twos complement format, According to the 16-bit two's complement format, it can be accessed through the digital interface SPI (3-wire or 4-wire) or I2C
• The ADXL345 is perfect for mobile device applications.t can be used for tilt sensing applications while measuring static acceleration of gravity, and it can also measure the speed of vibration caused by dynamic added motion or caused. Its high resolution (3.9 mg / LSB) enables measurement of tilt angle changes of less than 1.0 , Use ADXL345 digital output timing acceleration, etc
• Appliactions: The GY-291 ADXL345 can used in Handsets, Medical instrumentation, Gaming and pointing devices, Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection, Portable gaming
• The gy-291 ADXL345 device offers a variety of special detection. Activity and inactivity sensing through comparing any axis acceleration threshold set by the user to detect the presence or absence of transport movable occurs.Tap any direction sensing detects single and dual vibration vibration make. Free-fall detection can detect whether the device is falling. These ones function can be mapped to two interrupt output pins
• Low power modes enable intelligent motion-based power management to a very low power consumption threshold sensing and active acceleration measurement. as low as 23 A in measurement mode and 0.1 A in standby mode at VS = 2.5 V (typical)
