PROBLEM

I would like to start growing crops but during summer it gets too hot and sometimes I need to water several times a day. Besides, water is a scarce resource which should be used only when required. Therefore, I would like to have a system that water the plants for me.

PLAN

Collect information about the humidity and the temperature of the soil and also get a prediction of the weather for the next days. Based on that, decide if the plant should be watered and in that case open the valve of the solenoid to water the plants. All this implemented in a portable Raspberry Pi (i.e. powered from solar power + using a 3G dongle)

BONUS

Learn about IoT infrastrcutures which might help in a big field to not only water but doing other useful stuff
