3. Natural pollination not possible in a controlled environment
4. Technology dependancy
While to make a viable business around vertical farming has many aspects like space optimisation, demand and supply rate, etc., in this project I want to concentrate on the technical aspects and make them modifiable when scaled to make a bigger farm.

I listed out the inputs and outputs to include in the design after studying some similar projects like [POWAR](http://www.pablozuloaga.com/POWAR.html), [Mixoponics](https://fab.academany.org/2020/labs/bahrain/students/muhja-aljaser/projects/final-project/), etc.
Inputs to include:
1. DHT11 - temperature and humidity sensor
2. Phototransistor - to measure ambient light intensity
3. Potentiometer / variable resistance - to control flow of water through pump
4. Potentiometer / variable resistance - to control grow light intensity

Outputs are:
1. 12V DC pump to pump water through a sprinkler system

With the help my instructor Steven, I developed a basic scheme for the electronics.

While making the schematic I realise not all sensors and actuators need to be on the PCB itself, some like the pump and the led and the DHT11 need to be at a different physical location on the designed box, so I need to add header pins and connect them using wires later.
To clarify this, I begin modifying my 3D CAD model on Rhino.
