HMI Sensor Network

Measure and report environment data using XBEE nodes and a browser based graphical user interface.

The nodes

This project was my senior design project for my last year of school at South Dakota School of Mines & Technology. My partner and I created shield boards for XBEE wireless modules. These shields made it easy to attach sensors for temperature, lighting, and humidity along with an indicator LED. The XBEE network used a self healing mesh network which made it easy to add new nodes or compensate for a missing node. The node’s signal needed to go through brick walls and so pro modules were the ideal candidates. Basic XBEE modules were also used in the network due to their availability.

PIC32 Breakout Board

Fri, 20 Feb 2015 00:00:00 +0000

A breakout board created in my Microprocessor Based System Design class for a PIC32 microcontroller. The board was a semester long project in which each student designed a board layout. The class then voted on the layout they liked the most and the winning layout was sent to a board house to have one made for each student.

Overview

We first breadboarded the basic layout needed to run the PIC32 microcontroller in a previous lab. A design with more features than this was a requirement for us to send the board to the board house. A valid design had to be able to fit in to a 3” by 5” clear case. The project had four feature levels that each student could choose from to use.
