GY-291 ADXL345 Triple Axis Accelerometer
The GY-291 ADXL345 Triple Axis Accelerometer is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. A sensor module based on the ADXL345 accelerometer integrated circuit.
Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°.
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. Freefall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins.
- Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical)
- Power consumption scales automatically with bandwidth
- User-selectable resolution
- Fixed 10-bit resolution
- 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)
- Patent-pending, embedded memory management system with FIFO technology minimizes host processor load
- Single tap/double-tap detection
- Activity/inactivity monitoring
- Free-fall detection
- Module supply voltage range: 4.0 V to 6 V
- SPI (3- and 4-wire) and I2
- C digital interfaces
- Flexible interrupt modes mappable to either interrupt pin
- Measurement ranges selectable via serial command
- Bandwidth selectable via serial command
- 10,000 g shock survival
- I/O voltage range: 1.7V – 3.6V
- Communication: SPI and I2C
- Operating temperature: -40c – 85c
- Dimensions: 3mm x 5mm x 1mm
- 1 x GY-291 ADXL345 Triple Axis Accelerometer
