DIY Environment Control System

Make an environment control system with Raspberry Pi. via instructables

In this project I show the construction of an Evironment Control System which is controlled with a Raspberry Pi.
This was for my eighth-grade STLP (Student Technology Leadership Program) project. More information about Kentucky’s STLP program is available at their website, which is:

Currently, I can use it to control a small table-top sized demonstration greenhouse. The system can scale to be much larger, however, since it uses relay boards to switch 120v outlets.

My goal was to develop an environment that would be optimal for a food-producing plant so that food and sustenance could be obtained in extremely urban areas, in places with rapidly changing climate, or even on other planets, such as Mars. The ECS system could also be used to grow plants in areas too far away from the optimal growing area to ship. I will do this by controlling three variables: temperature, moisture, and light.

I used temperature and moisture sensors to relay information to the Raspberry Pi computer, which uses the information to decide when to turn on a water pump or a heating device. I also drive an LED grow-light in a computer controlled day-night cycle. In order to show progress as the plants grow, I use a computer controlled camera mounted within the dark enclosure to track the progress of the plants.
