Autonomous garden watering

This project builds off of my earlier motor control project -

The aim of the project is to create an autonomous garden watering and management system.

The inputs from the soil moisture sensor along with the temperature and humidity sensor will serve as a measure of how much water the plant needs. Using that information, the dc pump will be used to supply water to the plants. This closed loop is the intended aim for now.

I am also looking to see what data I can log and analyze from this project. It will be interesting to plot trends and analyze effects on varied environmental conditions on the growth of the plants.
