After nearly losing  a few plants at work with extended weekends with all the snow, I figured it’d be nice if there was a way for my plants to get water while no people were around. I’ve been toying with Arduino for a little bit now, and believe I’ve found a great project to use it with!
I’m going to make an automatic plant watering system!
My plan is to hook a moisture sensor up to my Arduino controller, then write up a little script to check the moisture sensor levels. The moisture sensor just gets inserted in the soil and is only a few dollars. So knowing when the soil is dry enough to need water, shouldn’t be too difficult to get working.
I’m still a bit puzzled on how I’m going to deliver the water, but I think attaching an electronic valve to the Arduino board would work out in this case. The plan to to hook up an IV bag or something similar, fill it up and let gravity and the electronic valve work their magic when the soil gets dry.
Also thinking of rigging up a solar power source, but will concentrate on those first two problem first.
Very excited to get started and will post updates and photos as I progress on this project.
