A Little Friend for My Plant

I wanted to make sure that my plant was getting the correct amount of sunlight. To much or little could harm it, and I wouldn't want to do that to my tiny guy. We are the best of buds and I value the green splash they add to my room. To reach my goal I used an ESP32 placed next to my plant to take measurements every second. To get light measurements a photoresistor was used as part of a voltage splitter. Then every ten minutes it averaged out these values and added it to an output list. Once 24 hours passed the output was taken and pasted into a spreadsheet where it could be interpreted. Despite how limited my sensor I was able to conclude that he is generally chill where he is only needing partial sunlight. But it would be good to use the blinds or shift him a bit from 2-3 to avoid the most direct light. In the future it would be good to revisit this with a SD card reader which would allow for easier data collection. With a wider dataset values for a given time of day could be averaged out to get a more applicable result.
