I know posts on automated plant care are very popular on Gadget Master, so I want to highlight this Arduino appnote - Smart Farm Irrigation System Using Arduino Edge Control.

Ancient civilizations built complex irrigation systems without the aid of modern technology or construction equipment. Can you design a model irrigation system using simple household materials?

Build a homemade drip irrigation system using PVC pipes and tubing to start efficiently watering your garden inside and outside.

Drain tiling is becoming more and more popular, and now Dyna Flo, an Oakes, North Dakota, company has designed a system to use drain tile water for irrigation.

Each irrigation system is designed to operate at a specific pressure. The water flow through each sprinkler depends heavily on this pressure, and larger nozzles are more sensitive to pressure changes.

Researchers at a university in Israel have warned that smart irrigation systems are vulnerable and could be drained by attack using a ‘piping botnet’.
