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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
