The Open Garden 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. We have also designed a web application that allows to store in a data base the information gathered and visualize it from a browser and iPhone / Android device. We have released it as open source code so that you can improve it and make it personal for your own product!!
Open Garden has been designed to work with both 220V Europe & 110V US.
