Wildcard Week
Semana 15: System Integration
Systems integration of the final project
During this week I worked on the system integration of my final project: a smart planter designed to monitor soil moisture and assist the user in plant care.
The objective of this stage was to unite all the components developed during the program into a single functional system. This includes sensors, electronics, programming, user interface, and the physical design of the product.
System integration allows all elements to work in a coordinated manner, transforming a set of individual prototypes into a functional and coherent product.
System Concept
My project consists of a smart pot that monitors soil moisture and tells the user when the plant needs to be watered.
The system uses an HL-69 Soil Moisture Sensor that measures the soil moisture level. This information is processed by the microcontroller and then displayed on an OLED Display Module.
Additionally, the system includes a Mini Speaker Module that emits an alert when the plant needs to be watered.
In this way, the smart pot establishes a simple interaction between the plant and the user, making it easy to monitor the state of the soil.

System Architecture
To better understand the system integration, a diagram was developed showing the relationship between the different components of the project.
The system flow is as follows:
The sensor measures soil moisture.
The microcontroller processes the information.
Data is displayed on the OLED screen.
When the humidity level is low, an alert is activated through the speaking module.
This diagram allows you to clearly visualize how each component interacts within the system.

CAD Design of the Product
To integrate all the components in an organized way, a physical structure was designed that allows the electronic system to be housed inside the pot.
The design was developed using CAD modeling tools, which allowed for space planning for each component, including:
humidity sensor
placa electrónica
pantalla OLED
módulo parlante
connection cables
This design facilitates assembly and improves the presentation of the final product.

Electronics Integration
Electronic integration consists of connecting all the components of the system so that they work in a coordinated manner.
In this project the following connections were made:
the humidity sensor connected to the microcontroller
la pantalla OLED conectada mediante comunicación I2C
the speaker module connected as an output device
These connections allow the system to receive information from the environment and communicate it to the user.

Packaging and Assembly
An important part of the system integration was the ordering and organization of the electronic components within the product.
Assembly methods have been implemented to keep components protected and organized, including:
electronic board assembly
cable organization
Fixation of components within the structure
This process allows the system to have an appearance closer to a final product.

Product Appearance
In addition to the operation of the system, the appearance of the final product was also considered.
The goal was to design a device that not only works properly, but also has a pleasing aesthetic and can be easily used by users.

Integration with Final Project Page
All system integration documentation is linked to the main page of my final project.
This integration allows us to understand how each of the processes developed during the program contributes to the development of the final product.
