Last week, I gave a brief introduction on what is HAB (Harmful Algal Bloom) and its impact (economic, environmental and health). I also gave its cause including the role of en-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/in-the-air-design-challenge/b/blog/posts/hab-monitoring-post-2-wireless-sensor-nodeTue, 04 Nov 2014 07:57:58 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:b5e11e0d-8692-42d7-9cd0-d6a2f35a49f2mcb11<p>I agree.</p><p>Trying to keep the pesky water out while allowing the sensors to be immersed will be the hardest/clever bit.</p><p>&nbsp;</p><p>You may want to experiment with anchoring your flotation device BEFORE adding any electronics, since the wear of the attachments points will be high as it bobs up and down.</p><p>I wonder if a 3-4m pipe-like device that is half submerged and absorbs waves will ride better over a longer time, rather than something that floats on the surface, and is constantly fighting it&#39;s anchor.</p><p>&nbsp;</p><p>You may even be able to incorporate an energy generator inside.</p><p>Mark</p><img src="https://community.element14.com/aggbug?PostID=19121&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/hab-monitoring-post-2-wireless-sensor-nodeMon, 03 Nov 2014 19:51:14 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:b5e11e0d-8692-42d7-9cd0-d6a2f35a49f2DAB0<p>Good post.</p><p>&nbsp;</p><p>I am really looking forward to how you put all of the sensors together.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=19121&AppID=102&AppType=Weblog&ContentType=0" width="1" height="1">
