This marks my third blog, detailing the progress of my UrbanRest Guardian project, aimed at monitoring anden-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/experimenting-with-extreme-environments/b/blog/posts/blog-3---urbanrest-guardian-prototype-construction-journeySat, 11 May 2024 20:54:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fa59de8d-2118-4b24-9877-1e55af856489javagoza1<p>[View:/cfs-file/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-fa59de8d-2118-4b24-9877-1e55af856489/IMG_5F00_1562.mov:640:360]</p> <p>I&#39;ve achieved promising results in identifying night sounds with the microphone inside the box. Though I still to fine-tune the gain levels programmatically, the progress so far is quite encouranging.</p><img src="https://community.element14.com/aggbug?PostID=27879&AppID=437&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-extreme-environments/b/blog/posts/blog-3---urbanrest-guardian-prototype-construction-journeySat, 04 May 2024 17:16:37 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fa59de8d-2118-4b24-9877-1e55af856489javagoza1<p>I have added an update with a demonstration of the operation of the capacitive keyboard, with a&nbsp; MPR121 sensor, behind the transparent lid of the enclosure. Although the distance imposed by the thickness of the transparent lid is above the limits that the manufacturer guarantees, by adjusting the sensor parameters I have managed to read the keys well. Another option that I have tried is as a proximity sensor, an option that allows you to launch proximity events without even touching the box, using all the sensors to create a virtual one.</p><img src="https://community.element14.com/aggbug?PostID=27879&AppID=437&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-extreme-environments/b/blog/posts/blog-3---urbanrest-guardian-prototype-construction-journeyThu, 02 May 2024 18:49:08 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fa59de8d-2118-4b24-9877-1e55af856489DAB2<p>Nice update.</p> <p>Are you going to monitor the temperature inside the enclosure?</p><img src="https://community.element14.com/aggbug?PostID=27879&AppID=437&AppType=Weblog&ContentType=0" width="1" height="1">
