PlantLink says... everything is just right.
I hooked up my PlantLink from OSO technologies last week, the first reading I got when I looked on the dashboard told me to Water My Plant. I'm using PlantLink for my schefflera umbrella tree. It is an important plant to me, it was my grandmothers. Her name is Susie Gipson (RIP), so naturally I call the plant Mama Susie's scheff in the dashboard. PlantLink lets you name the plants and such. Kinda neat.
When the plant will need watering again, I will get a text alert to water it. If the plant is very much in need of water, I will get an urgent text alert reminding me of the critical nature of neglecting ones plant.
sensor in the soil... pretty easy.
