Oil Tank Level Monitor

<p>With COVID, we are home a lot more. We were curious how this was affecting our oil usage. We have a 275 Gallon vertical tank. It has an extra 2" vent hole on the top of the tank. I used this to insert a 2" PVC pipe connector. I designed and 3D printed an insert to hold a Particle Proton WIFI microprocessor and an ultrasonic distance sensor. I came up with two different approaches to convert the measurement from the tank opening to the top of the oil to gallons of oil remaining. The information and alerts can be sent to your cell phone. It works with IFTTT and Blynk.</p><p>The parts I used cost less than $40:</p><ul><li>Particle Photon WIFI microprocessor ( <a href="https://www.sparkfun.com/products/13774">https://www.sparkfun.com/products/13774</a> )</li><li>HC-SR04 Ultrasonic Sensor ( <a href="https://amzn.to/38VGMH5">https://amzn.to/38VGMH5</a> )</li><li>5V 2A USB micro power supply ( <a href="https://amzn.to/32YLBeS">https://amzn.to/32YLBeS</a> )</li><li>female to female jumper wires ( <a href="https://amzn.to/2HiaiLG">https://amzn.to/2HiaiLG</a> )</li><li>Permatex Ultra Black Oil-resistant RTV ( <a href="https://amzn.to/3lFizIq">https://amzn.to/3lFizIq</a> )</li><li>2" PVC Schedule 40 Plug ( <a href="https://amzn.to/38UKMaB">https://amzn.to/38UKMaB</a> )</li><li>2" PVC Schedule 40 NPT adapter ( <a href="https://amzn.to/3fkwp0E">https://amzn.to/3fkwp0E</a> )</li></ul><p>As an Amazon Associate I earn from qualifying purchases.</p><p>After I did my project, I found another similar one: <a href="https://blog.vpetkov.net/2017/11/12/diy-monitor-heating-oil-tank-gallons-with-pushbullet-sms-and-email-alerting/">https://blog.vpetkov.net/2017/11/12/diy-monitor-heating-oil-tank-gallons-with-pushbullet-sms-and-email-alerting/</a></p><p>I also found a commercial product: <a href="https://amzn.to/2IKdkbT">https://amzn.to/2IKdkbT</a></p><figure class="media"><oembed url="https://youtu.be/A4UfaZbKgg0"></oembed></figure><h3>Print instructions</h3><p>Print using supports only on the table and use PETG since it is oil resistant</p>
