<p><span style=”font-family:Arial,Helvetica,sans-serif;”><strong><span style=”font-size:18px;”>DESCRIPTION</span></strong></span></p>

<ul>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>GY-291 ADXL345 3-Axis Accelerometer is a sensor board based on ADXL345 accelerometer integrated circuit.&nbsp;</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to &plusmn;16 g.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>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.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Well suited for mobile device applications.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0&deg;.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Several special sensing functions are provided.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Tap sensing detects single and double taps in any direction.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>Freefall sensing detects if the device is falling.</span></span></p>
</li>
<li>
<p><span style=”font-family:Arial,Helvetica,sans-serif;”><span style=”font-size:14px;”>These functions can be mapped individually to either of two interrupt output pins</span></span></p>
</li>
