“Brilliant setting up with the Luftdaten script and monitoring the local air quality, a noticeable deterioration being observed as Covid lockdown is increasingly ignored and aircraft are returning to the skies. Would be good to explore the other sensors at the same time as sending to Luftdaten.”
“Nifty little measurement device including a really nice little screen. Example code provide gives lot’s of ideas. I currently run it with a website in it so I can read the values everywhere and a python script showing the values on the screen. I wonder if air quality is really measurable worse the this COVID-19 lockdown period is over.
At least I can measure it myself.”
“I didn't get the little display to work until I bolted the Enviro+ together to the Raspberry Pi Zero W v1.1 that as explained above. Both Enviro+ and PMS5003 supply all their data. It now works perfectly for all of the enviroplus-python directory's applications. Neither did the PMS5003 issue any data. Now all data is displayed and I like using "python combined.py" that shows all data all the time.
I really can't get something in the Phil King article in Magpi Issue 92, p. 66-69 where on p.68 it shows (top left) how to get the diagram working. I see others have raised issues abut that in Pimoroni, too.
I am intending to try to run it outside with a Lithium Polymer Battery 3.7V and 6500mAh that will be being recharged by an Adafruit solar panel (13.5 cm x 11 cm) that provides 6V and 2W. For 2-3 years 2009-2012, I used that approach for building and running a Raspberry Pi original version that was taking photos once every hour of birds on a garden birdbath. Obviously, every few days, I also had to recharge the Lithium Polymer Battery. I still have a plastic box I used that contains the Lithium Polymer battery and a tiny circuit board (Adafruit) that lets the solar panel charge the battery, but also allows a mains plug cable to be plugged in to recharge the battery. Our house doesn't have any outside mains socket and I don't want one. I also feel feeding mains cables out of a window is not safe.”
“The GPIO header on my original unit was not fully soldered when I received it. I sent a message over to Pimoroni and received a quick and helpful response. They'll be shipping out a new unit and allowed me to keep the original one to see if I can fix it.
I also have a few other items from Pimoroni such as the unicorn pHat and the Unicorn Hat HD which are really fun. We use them with a simple API to add visual alerting when one of our systems/sites has a problem.
The quality of the boards is always (except this one time) fantastic, very aesthetically pleasing, and the documentation and libraries are very well written and easy to follow.”
