So we are going to need six room controllers. So we will need several sensors in each of the rooms which in turn feed in the correspondinen-USTelligent Community 12https://community.element14.com/challenges-projects/project14/remote-monitoring-control-devices/b/blog/posts/smarthab-remote-sensing-and-control-iii-sensorsTue, 06 Aug 2019 13:15:11 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:767b360b-6f60-439b-8a1c-2cda7a603c5dwonko_the_sane1<p>Unless I&#39;ve misunderstood your arrangement, I think you want a differential pressure sensor across your filters. The pressure drop will increase over time with accumulation of dust, which results in either&nbsp; your fans working harder to push the same amount of air or pushing less air for the same work. </p><p>Having flow meters both sides of the filter shouldn&#39;t show any difference when compared due to conservation of mass. Except if you&#39;re recording flowrate over time, in which case 1 meter on one side or the other should be sufficient to show a decrease in flowrate due to dust buildup.</p><img src="https://community.element14.com/aggbug?PostID=7382&AppID=237&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/project14/remote-monitoring-control-devices/b/blog/posts/smarthab-remote-sensing-and-control-iii-sensorsThu, 04 Jul 2019 18:55:29 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:767b360b-6f60-439b-8a1c-2cda7a603c5dDAB0<p>Those components should give you good environmental assessment and control.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=7382&AppID=237&AppType=Weblog&ContentType=0" width="1" height="1">
