Successfully assemble and operate an Indoor Automatic Plant Watering System (APWS) using Raspberry Pi 3.
Goal 1: Design the model
It is important that we have the 3D printed parts modeled and measured in
software before buying other accessories accordingly.
The parts that need to be modeled and printed are: Raspberry Pi and LCD housing,
Sensors' housing. Before doing this stage of the project, we will need to sketch out the
ideas and the rough design of the casings before 3D model them to save time and effort.
After that, a simple model of the whole system will also be made in 3D so that we can
estimate the materials that we need to assemble it.
Goal 2: Write the codes for the software to run on Raspberry Pi 3
This is a crucial step for the whole model to function as this will be the 'brain' and control other components of the product. At this stage of the project, the program only need to read the moisture level of the soil and activate the pump accordingly. Moisture levels will be set at different values for different types of plants or according to the user’s need.
Goal 3: Acquire all the necessary parts and assemble them
For this project, we will need to buy several parts that is required for the model to
function.
These parts will include a Raspberry Pi 3, 3.5in LCD screen to monitor the system,
Packet of GPIO Wires, Soil moisture sensor(s), metal bars for the frame, 8 Channel Relay
Module, Hydroponic Light, small water pump, PVC tubes for watering the plants, soil,
seeds/plants of choice.
