**Why smart greenhouse?**
The main reason why I have came up with this project idea is I wanted to convert all the greenhouse which are at our mega farm at my institute into a smart one. There are more than 50 greenhouses which were currently opperating mannually. First I will build a small prototype in my Fab academy course and once I graduate fab academy I will apply the same concept at a larger scale at our Fablab. After that, then I will integrate it with my college farm. I have other reasons to come up with this idea which I have mentioned in my problem statement below.

# SOME CHANGES FOR THE FINAL PROJECT
Initailly I thought of using 4 input device and 5 output devices.
After discussing with my remote mentor Takesen and Rico, we have decided to use only 2 input devices and 4 output devices.

# **Detail of My Final Project**
From the begining of the fabacademy I was thinking of making a portable greenhouse so that after I finished my course I can take it with me to the college. For that I have use a light material which is easily available and inexpensive.

There are lots of unused wooden planks and plyboard all around our fablab. I collected some of them and stored inside the lab so that once I finished my designing I will cut them as per my design.

Previously I used EAGLE to make PCB design during electronic design and electronic production week. Later I switched to KICAD to design my PCB boards as KiCad is open source and easy for me to use.
