Senior Design 1
For Senior Design 1, James Utke and I chose one of a list of different projects to complete for our semester design project. The project we chose was the Photoelectric Switch.
The Photoelectric Switch uses a light sensor across a 36” door width to detect if something passes through the door. If something breaks the light beam, an audible alert will sound.
From this project, I learned the importance of documentation and keeping up with the documentation. I also learned that there are a lot of revisions that go into a design project, even a small one. The schematic shown below is the final revision of the design after consulting a faculty member several times to correct and refine our design.
This schematic is the Circuit Lab schematic of the design outlined with the major sections of the design
This is our schematic made with verified parts using Upverter
Here we have the overview of the 2" x 2" two layer PCB
This is the top copper view of the PCB.
