FINAL PROJECT DESCRIPTION.¶

INTIWAN QARPAY is an automatic irrigation device capable of working with up to eight water pumps to feed large or small sections of arid land. These devices will help ensure crops are always well-watered, as they can be integrated with various irrigation systems, such as drip or high-pressure irrigation nozzles. Technology is now within reach, thanks to a small device. It was designed, developed, and assembled in the Digital Manufacturing Laboratory (FABLAB) of Continental University, focusing on the important issue of water and healthy eating, even without much water. It is a self-sustaining energy system, equipped with a solar panel and a battery that provide sufficient energy for its operation. The idea arose from the need to generate low-cost devices that can be replicated and distributed to local communities or non-governmental organizations with which we currently have active ties.

3D Design.¶

For the 3D modeling part, Invetor software has been used. This software helps us a lot to have a similar and very real design so that it can be implemented in our project.

Project’s name¶

For the presentation of my final project, called INTIWAN QARPAY, it is in allusion to the use of the composition of two Quechua words:

INTIWAN = What does it mean with the sun.
QARPAY = Which means watering (land or farm)

As we indicated the use of the Quechua word INTIWAN, the sun, we use solar panels for our IRRIGATION SYSTEM project for use in remote places where there is no access to the use of household electricity. The use of our INTIWAN QARPAY prototype will be located in remote places where we want to have irrigation efficiency, time-based dosing and above all the possibility of operating with the solar panel system, in addition to being super simple in the way of handling and operation.

Project Logo¶

In the logo section I use the symbolism of the sun, water in the form of a puddle and the Quechua typography for its name.

My Project Idea (SLIDE)¶

The project is also designed for use in the irrigation of vegetables such as spinach, cabbage and chard, among others rich in iron, for use against anemia, in rural areas. The modularity of the system can vary in construction and application forms, a self-sufficient water system or a pumping system by electric pumps. It will be our decision.

Electronic Design.¶

The electronic design was done using KiCAD software, a necessary tool for the final prototype development process. Neil, who last year told us that it was necessary to work with the SEEED XIAO RP2040 card to be able to control the submitted projects.

We’ll start by selecting the components from the library and then connecting them together, ensuring they meet the voltage inputs and input and output signals to avoid any subsequent issues. It’s important to review each manufacturer’s data sheets to see how each component behaves in certain situations and the appropriate configurations.

Once the entire design process is complete, the work on the PCB board will be sent to be carried out, according to the requirements, measurements and cutting parameters seen in the previous assignment.

2D and 3D Modeling¶

The 2D and 3D designs for this improved version were created using ONSHAPE. I personally really like this program because it allows me to connect from anywhere. The images shown show the back panel of the case and its cover, which houses the fundamental electronics of this project.
