Arduino is a platform that combines hardware and free software to turn into reality the dreams of farmers more geek, are getting the foundations of a new much more efficient landscaping in the use of water in the garden. It’s a new generation of irrigation systems that considers the needs of water the plants in the garden, and what you say not a programmed timer. Systems that anyone can build (DIY), very cheap, modular, extensible, you can adapt to your needs and finally share with the rest of the world. The systems are composed of a microcontroller (Arduino board), a set of sensors for temperature, humidity and light (which you can build yourself) and the rest of elements, switches, solenoid valves, modules of transmission, wifi, etc. to create a system as complex as you need.
Gardenbot is an open project for the creation of a system of monitoring of the conditions of a garden that uses Arduino to the current state of the soil to be viewed on a computer. Garduino Shield is another project is open, similar to the previous one which offers you, step by step, the creation of an automated irrigation system based on ambient light, moisture and soil temperature conditions. Voltaic Systems sells a kit Garduino supplemented with solar panels and a battery, so you can get up and running in places where there is no electricity. On Instructables, you can see instructions – step by step – to create systems of irrigation and automatic lighting that also alerts you of the conditions of the Earth via twitter.
