Water meter - AI-on-the-edge

prusaprinters

<p>This mount is designed to attach an ESP32-CAM microcontroller to a water meter. Together with the open source firmware "AI-on-the-edge" (<a href="https://github.com/jomjol/AI-on-the-edge-device">https://github.com/jomjol/AI-on-the-edge-device</a>) of the user Jomjol it can read the water meter automatically and send the current counter status to a server via MQTT.</p> <p>You can find my tutorial for this project on Youtube: <a href="https://youtu.be/iUgxwbfkIqU">https://youtu.be/iUgxwbfkIqU</a></p> <p>It is a good idea to print the model with black filament to avoid unnecessary light reflections on the meter glass. I realized this too late, so I printed the mount in white, which also works with a little fiddling.</p> <p>In order to create controlled conditions during photography, it would of course have been even better to design a closed housing. However, this was countered by the longer printing time and higher printing costs. Since my meters are located in a permanently dimmed utility room, I opted for this solution. The advantage is that you can still read or check the meter values manually without removing or converting them.</p> <p>Remixes and improvements of my model are welcome, you can find the FreeCAD model in the download section as well.</p> <p>Jomjol, the AI-on-the-edge-Developer, has also a Thingiverse-Account:<br/> <a href="/jomjol/">https://www.thingiverse.com/jomjol/</a></p> <p>And he has also an alternative Watermeter-Bracket:<br/> <a href="https://www.thingiverse.com/thing:4573481">https://www.thingiverse.com/thing:4573481</a></p> <p>Update:<br/> 2021-07-17 Opening for the ESP32cam increased to provide enough space for the micro SD card</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Anet</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>A8</p></div><strong>Rafts:</strong></p> <p>Yes</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div><strong>Resolution:</strong></p> <p>200</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div><br/> <strong>Filament:</strong><br/> Eryone PLA </p> </p></p></p> Category: Electronics
