Hi Growers -
I'm hoping you can help me and your fellow growers out.
I built an android app that uses the light meter in your smartphone to convert the LUX reading to PPFD.
The app will be completely free once it's ready for the app store.
The conversion factor used to go from LUX to PPFD depends on the selected light source.
I was able to get these conversion factors from a few manufacturers, but the accuracy of the light meter in the various smart phones is something I'm hoping this community can help me figure out and account for in the app.
Here's the problem...A Samsung S7 will likely have a different Lux reading than a Pixel 3 XL. Without knowing the exact Lux reading of a particular light, at a specific distance, and for the users exact brand and model of smart phone, the readings won't be as accurate as they would be otherwise.
If you're willing to help a brotha out, please install a lux light meter on your smart phone and answer the questions below...
1. Phone brand and model?
2. Light source? - please be specific
3. Total Watts it's pulling from the wall?
4. Lux reading at exactly 12 inches
5. Lux reading at exactly 18 inches
Some lux meters in the app store:

Thanks and happy growing!
