I have a project that I'm currently working on. We have built a green wall, wich consists of plants on a wall
Now, we have a pump situated at the bottom that waters all the plants. There is an arduino board that decides when to put the pump on. Powering it is a solar panel and wind turbine. We want to know how much energy we have saved by using the solar panel and turbine.
How do I measure the amount of energy, in Wh, used from 00h00 that day? Is there a library? Or is this not possible with Arduino?
Thanks a lot.
To clear up some things
No, the pump is not fueled directly by the Arduino pin. We are using a motor shield.
Yes, there is an accumulator in the circuit. The solar and wind power recharge a battery which in turn powers the components.
I would like to know the entire energy consumed, not just the pump.
