                                             Smart Greenhouse

Control the light, watering, temperature, and humidity of your greenhouse – automatically.

                                                                                                                                  Kevin Farnham

      Smart Greenhouse, one of three professional category winner in the 2014 IoT Developer Challenge, is an Internet of Things (IoT) device and application that monitors and controls a greenhouse environment. The concept for Smart Greenhouse came into being after the core team – Dzmitry Yasevich, Pavel Vervenko, and Vladimir Redzhepov – attended JavaOne Russia in April 2013. There, the team saw presentations of a smart house, various robots, and other devices, all controlled by Java.

      Yasevich notes, “We were impressed by these solutions and had an idea to do something like that. Pavel Vervenko suggested making an automated greenhouse. Everyone liked the idea!”.

      First, the team selected the hardware. “We started to use Raspberry Pi as a basis”, Yasevich says. “It is a compact but fullfedged computer with 700 MHz and memory at 512 MB. This system costs around $35”.

      However, early on, a safety concern arose. “Current under high voltage passes in the greenhouse, and there is an automatic watering system, so it was necessary to properly consider all the aspects related to insulation”, Yasevich says.

      We take software for granted, but it's obviously crucial to getting any work done on a computer. It's what makes computers and smartphones and tablets (and these days, for that matter, cars, televisions, and microwave ovens) actually do things. Without it, your computer or other device is simply a case with nice buttons and lights.

                             How open source has changed the hardware environment

      While open source software is a relatively well-known concept by comparisons, the idea of open source hardware isn’t quite as publicized. In fact, few people are aware that there are quite a few organizations offering open source hardware, which meansthey have made all information pertaining to their products freely available, including designs and schematics, bill of materials information, and printed circuit board layout data. Generally, open source software is used in the original design, which provides evenmore benefits.

      The driving ideology behind open source hardware is that anyone should have the freedom to:

• Use the device for any purpose.

• Study how it works and make any changes.

• Redistribute the design of the device and the device itself.

• Enhance the design as well as the device and make those improvements freely available to the public so all can benefit.
