Home based plant moisture monitoring solutions using Raspberry Pi and Arduino. We created several different dashboards including web hosted options and a custom cell phone application that connects to the Pi through Bluetooth.
Everything is open source under the MIT license. Would love feedback, contributions!
This includes a lot of good setup for networking Arduino, Raspberry Pi, and Android mobile devices. It was a very fun project to put together! Also handy for anytime buying a kit with the raw components we used as we found the manufacturers instructions for those to be slim.
