Feature

●Product Introduction: The GY-291 ADXL345 is a small, thin and ultra-low power consumption 3-axis accelerometer with a high resolution (13 bit), measuring range of ± 0.6 oz (16 g)
●Module Features: GY-291 sensor digital output data is 16-bit 2 supplementary format and can be accessed via SPI (3-wire or 4-wire) or I2C digital interface
●High Definition: The GY-291 ADXL345 sensor comes with a high resolution (3.9 mg / LSB) that allows you to measure the angle of inclination less than 1.0°
●Low Power Mode: ADXL345 sensor supports motion based intelligent power management for threshold sensing and motion acceleration measurement at low power consumption
●Applications: The ADXL345 is ideal for mobile device applications and measures not only static gravity acceleration in tilt detection applications, but also dynamic acceleration caused by movement and impact
