2Pcs GY-291 ADXL345 3-Axis Digital Three-axis Acceleration of Gravity Tilt Inclination Module IIC/SPI Transmission

• ADXL345 is a small, thin, low-power three-axis accelerometer can be high. Up to ± 16 g accelerometer with high resolution (13) measurements. Digital outputs according to a 16-bit twos complement format, can be accessed through the digital interface SPI (3-wire or 4-wire) or I2C.
• ADXL345 is well suited for mobile device applications. It can tilt sensing applications measuring the static acceleration of gravity, it can also measure the dynamic add motion or shock caused speed.
• 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.
• 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.

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. 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 Package inlcuded: 2 X GY-291 ADXL345 3-axis digital acceleration module 2 X 8P pin header
