Open Garden is an Open Source alternative to commercial home automation to remotely control your indoor and outdoor plants. The platform consist of three different kits, each ready for a specific kind of growing plant scenario: indoor (houses and greenhouses), outdoor (gardens and fields) and hydroponics (plants in water installations).

The platform allows to control the state of the plants by sensing several parameters:

• Soil moisture (Indoor & Outdoor kits)
• Temperature + Humidity + Light (All kits)
• Water sensors: pH, Conductivity, Temperature(Hydroponics kit)

Then it uses different types of actuators to modify the state of the plants by irrigating them or activating lights and oxygen pumps:

• Water pump + Droppers for Drip Irrigation (Indoor kit)
• Electro valve + Sprinkler for Sprinkling (Outdoor kit)
• Oxygen Pump + Growing Light (Hydroponics kit)

The nodes send periodically the information to the Gateway that uploads the data to a web server by using any of the available wireless interfaces (WiFi, GPRS, 3G).
