/challenges-projects/design-challenges/in-the-air-design-challenge/b/blog/posts/firecracker-analyzer-week-1-system-design-and-redesignI had already proposed a design but it was a bit rough and after talking to some sensor vendors, I found that not only are gas sensors expensive but most of them might not be suitable for outdoor use at all. Hence I have cut down on the sensors and aen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/in-the-air-design-challenge/b/blog/posts/firecracker-analyzer-week-1-system-design-and-redesignFri, 07 Nov 2014 22:21:41 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:354a4ed4-6400-4860-abed-4b05a6681fcdDAB1<p>Very good post.</p><p>&nbsp;</p><p>I am really interested in seeing how you use the battery booster pack with solar collectors.</p><p>I had a similar idea that I was hoping to get to.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=19144&AppID=102&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/in-the-air-design-challenge/b/blog/posts/firecracker-analyzer-week-1-system-design-and-redesignFri, 07 Nov 2014 10:49:54 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:354a4ed4-6400-4860-abed-4b05a6681fcdshabaz1<p>Hi Inderpreet,</p><p>&nbsp;</p><p>Nice diagram. It&#39;s great that you&#39;ve got remote and local nodes - quite a major project, good idea to get the PCBs designed asap as you say.</p><p>Well spotted with the solar panel/BoosterPack idea - looking forward to seeing your blog post!</p><p>&nbsp;</p><p>Which solar panels are you planning to use?</p><p>I have been experimenting with one from Farnell, but the one I picked was quite large (140x100mm). I guess you need a small/light one for your remote nodes.</p><img src="https://community.element14.com/aggbug?PostID=19144&AppID=102&AppType=Weblog&ContentType=0" width="1" height="1">
