Winter in my area is not a snowy winter dream. Maybe that’s why I am not very much into winter. Winter is a season I always wait to pass. While waiting, I prepare for spring. And this spring I want to build a solution for a problem we always have in summer: Our strawberry plants shrivel to death during our summer holidays. So I decided to build a automatic watering machine for them.
My first step is developing a soil moisture sensor. I checked out different implementations and found that capacitive sensors are best as they do not emit unhealthy things into the soil.
