The information listed in under the <strong>Features</strong> tab is correct, with 18 antennas, since this product is the Developer version.</p>

</code></pre></p>

Some of it is documented in the tutorial => <a href="https://learn.sparkfun.com/tutorials/getting-started-with-walabot#example-sdk" rel="nofollow">Getting Started with Walabot: Example SDK | Imaging - Short Range</a>. If you were reading a pipe behind a wall or table:<p></p><div class="center-block text-center"> <a href="https://cdn.sparkfun.com/assets/learn_tutorials/7/2/4/WalabotShortRangeImagingParallelObject_1.jpg" rel="nofollow"><img src="https://cdn.sparkfun.com/r/600-600/assets/learn_tutorials/7/2/4/WalabotShortRangeImagingParallelObject_1.jpg" alt="Move Walabot Developer Parallel To Pipe"></a> </div><p>It would look like this in the SDK for Windows:</p><p></p><div class="center-block text-center"> <a href="https://cdn.sparkfun.com/assets/learn_tutorials/7/2/4/WalabotSDK_Imaging-ShortRangePipeParallel.png" rel="nofollow"><img src="https://cdn.sparkfun.com/r/600-600/assets/learn_tutorials/7/2/4/WalabotSDK_Imaging-ShortRangePipeParallel.png" alt="Walabot Developer SDK Short Range Imaging Parallel"></a> </div><p>This is how the values may look when using it with Python on a Raspberry Pi:</p><p></p><div class="center-block text-center"> <a href="https://cdn.sparkfun.com/assets/learn_tutorials/7/2/4/WalabotPython_BreathingAppInhale.png" rel="nofollow"><img src="https://cdn.sparkfun.com/assets/learn_tutorials/7/2/4/WalabotPython_BreathingAppInhale.png" alt="Walabot BreathingApp.py Inhaling"></a> </div><p>Those are a few basic examples to get started. You would need to adjust the code for your application. Eventually, you could develop a project similar to the Android app to see the orientation of the material behind a wall similar to the SDK for Windows, map an image, and determine the dielectric properties of the material (like metal, plastic, or wood) => <a href="https://youtu.be/p3gDX75a_b4" rel="nofollow">https://youtu.be/p3gDX75a_b4</a> . I have not tested the Walabot Developer's app for Android.</p></p>
