I have no clue about measuring air quality. I don't even know what numbers are good or bad.</div><div><br data-mce-bogus="1"></div><div>We want to make changes to the house. One change includes pulling up all carpet now, living with the subfloor for a month or so, and then laying the wood floor. Pulling the carpet now addresses allergens. I need time to source the wood. I told the wife that we can't just make all these changes without knowing those changes had a positive effect. Measure, adjust, and measure. </div><div><br data-mce-bogus="1"></div><div>I need to validate the code, the values, and sensor placement. I also need to remove the chains of USB so I can easily transport this device around the house. I do not have wifi shield. I have many of the $3 UNO tiny devices. I'm thinking the FASTEST path of breaking that chain is to pair up the UNO with a NodeMCU and use the uart of the NodeMCU to read the values and then use wifi to submit them. rrdtool will do the rest.</div><div><br data-mce-bogus="1"></div><div>Eventually I could just move the code to the NodeMCU and I will not need to tiny UNO. The requirements of sampling are stringent. I wanted to try this out with firmata to demonstrate firmata capabilities with our device, but I'm thinking the requirements are too strict. </div><div><br data-mce-bogus="1"></div><div>In honor of all federal agencies are now prefixed with "Obama's" I'm calling this device "Obama's EPA's Air Quality Meter" :)</div><div><br data-mce-bogus="1"></div><div>Yep, print it on white letters and post it to the nicely black painted scrap wood I'll use to mount it. You should see the "fake TV" I made and use when we go on trips.</div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div></div></body></html>
