In parts one and two of this series, we built a program to monitor the moisture level in a plant and a program to convert our readings into a chart. The final step is to create a web page that lets us see our chart and download our logging file. That's what we are going to cover in this tutorial. If you have not already read parts one and two, I'd recommend doing that before continuing. You can find links to these tutorials at the end of this post. Without any further ado, let's get started.
In the last part of this series, I walked you through how to create a program that logs the moisture levels in your plants. If you haven't already read that tutorial, I'd recommend going back to it before reading on. If you have, you are ready to advance onto the next stage of your journey toward building a plant monitor dashboard: showing your plant data on pretty charts. That is the topic of this tutorial.
Do you sometimes forget to water your plants when they are in need of some water? I am the sort of person that writes down "water plants" but forgets about it for a day or two before finally watering my plant. My plant is alive and well but I could do better. That's one reason why I decided to research if there were ways in which I could monitor the moisture levels in my plant soil. Moisture levels are directly correlated with when a plant needs watered: the drier the soil, the more the plant needs watered.
