ADXL345 Triple Axis Accelerometer Board

Description

ADXL345 Tripple Axis Acceleromet er Board is a small, thin, low-power, 3-axis accelerometer with a high resolution (13-bit) measurement at up to ±16 g . Digital output data is format as a 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I 2 C digital interface. The ADXL345 Tripple Axis Accelerometer Board 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 (4 m g /LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent-pending 32-level first-in, first-out (FIFO) buffer can be used to store data to minimize host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. Applications : Pointing devices. Handsets. Medical Instrumentation. Gaming. Industrial instrumentation. Personal navigation devices. Hard disk drive (HDD) protection. Fitness equipment. defense and aerospace. Note: This package does not include the Arduino board, you have to buy it separately. Features : Ultra-Low Power: 40µA in measurement mode, 0.1µA in standby@ 2.5V. Free-Fall Detection. Tap/Double Tap Detection. Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command Wide temperature range (−40°C to 85°C). 10,000 g shock survival. Support 5V/3.3V voltage input, onboard RT9161 power chip, lower pressure drop faster than 1117, the faster load speed of response, very suitable for high-noise power supply environment.
