I have ~12 houseplants which are very dear to me. I am planning a 5 week trip and wont be around to water them. I want to create an app based plant irrigation system that would detect moisture level of each plant, notify me, and water them accordingly. I am fairly new to working with Arduino board so would appreciate help and support.
A few questions I have are -
Will I be able to control operations for individual plants via one arduino board?
What sensors and modules would I need for setup.
Any documentation around how to translate arduino readings to an iOS app.
