To detect soil moisture, you can pick up a cheap breakout board online. The project also uses a Raspbian-compatible plug-and-play webcam to provide the video, and the Motion Linux tool to handle the monitoring.
A hydroponic garden might not be the first place you would expect to find a single-board computer, but in this project it provides essential video monitoring and moisture detection. Growing pesticide-free, hydroponic, or organic hydroponic produce has never been easier – especially now that the Raspberry Pi is here to help. This article appears in The MagPi #62 and was written by Kent Elchuk, a Raspberry Pi enthusiast, web developer, and gardening author who is likely to be tinkering with code or working in the garden.
Why not use your Pi to build a hydroponic garden? Eat better and dodge those expensive food prices! Hydroponic growing is efficient, healthy, and easy to maintain – especially when you can build a system that allows you to leave the garden, and monitor it remotely from an internet connection, for under $50 (£38).
