[ale] Sensor nuts

[Chris Fowler]

Any sensor nuts here? 

Yesterday Amazon dropped off a Sharp GP2Y1010AU0F and I have it working with an UNO. 

Communications and code I can do. I have no clue about measuring air quality. I don't even know what numbers are good or bad. 

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. 

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. 

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. 

In honor of all federal agencies are now prefixed with "Obama's" I'm calling this device "Obama's EPA's Air Quality Meter" :) 

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.
