Reddit reviews Adafruit TSL2591 High Dynamic Range Digital Light Sensor [ADA1980]

This is a Sky Quality Meter used for measuring the light pollution and skyglow at your location. It outputs values in uW/cm^2 for the infrared
and visible specturm and your limiting magnitude in Mag/arcsec^2.


It should be mentioned that these are all Amazon Prime links with two day shipping. If you can wait longer then, you can certainly get these components for far cheaper.

You will also need an enclosure and a battery box or some other way of connecting power to the voltage regulator. I 3D-printed my enclosure but, I'm sure you can get
them cheap. As for a battery box, I use this:

I have no idea how to price the electrical tape you're going to need in order to cover the miniature star that is the power LED on the Pro Mini.

I suppose you could just desolder it. I'm not that brave. I used a 1/2 piece of black tape and blanketed the LED. Hopefully, not that much light will leak.

No worries.. I'm glad to share whatever I have, but it's all kept together by spit and ducktape atm.. The co2 is done with:

and some code I grabbed from:
https://hackaday.io/project/5301-reverse-engineering-a-low-cost-usb-co-monitor/log/17909-all-your-base-are-belong-to-us
https://github.com/wooga/office_weather/

It's an usb connection, gives co2 and temperature.

The other stats come from:

• tsl2591 (adafruit) / lux sensor : https://www.amazon.de/gp/product/B00XW2OFWW
  
• sht31 / high accuracy temp/humidity - https://www.amazon.de/gp/product/B07912W5NK
  
  Using Home Assistant to push everything to and prometheus+grafana for the dashboard. The outside temperature/humidity is just Home Assistant that pulls it from yr.no.
  The VPD value calculation I put in the sht31 python script.
  
  Home Assistant / prometheus / grafana don't run on the Pi.. only the sensors / stats gathering.
  
  If I find some time, I'll see if I can put it on github.

If so, can you tell me how you wired it? Thank you!
