AOICRIE 6PCS GY-291 ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module with IIC SPI Transmission for Arduino (6PCS)

• ☀FULL RESOLUTION: where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges)
• ☀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.
• ☀COMMUNICATION: It uses both I2C and SPI (supports 3-, 4-wire SPI) interface.
• ☀WIDELY APPLICATIONS: Handsets, Medical instrumentation, Gaming and pointing devices, Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection, Portable gaming.
• ☀ULTRA LOW POWER: as low as 23 μA in measurement mode and 0.1 μA in standby mode at VS = 2.5 V (typical).

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
