Below you can see a few concept pictures and a short text explaining the idea for my fully automated spacebucket, a greenhouse in a very cramped growspace.
The current idea is, that a camera, temperature and humidity sensors (both soil and air) are connected to the Raspberry Pi Zero W. The data is then beeing pushed to the Raspberry Pi 2 where it gets saved (for visualization). Furthermore, the Raspi 2 controls various devices to influence temperature and humdity as well as water the plant inside the greenhouse. Those devices are controlled through a Gertboard, since the Raspi can't handle that high voltages.
(The caption under the wifi signal says "temperature, air humidity, soil humidity, pictures")
