Senior Project: Presentation 1
An Open-Source Remote Monitoring
System
![Page 2: Senior Project: Presentation 1](https://reader036.fdocuments.in/reader036/viewer/2022062301/56815aa3550346895dc830f7/html5/thumbnails/2.jpg)
What?An open-source monitoring system for
remote solar power systems
Two Parts:
1.) Hardware Component: Interfaces with charge controller, transmits data
2.) Software Component: Stores and analyzes data

Why?Existing products are expensive, limited,
and proprietary
RM is an important aspect of decentralized power generation
Individuals should be able to take their own initiatives

Inspiration?
Why doesn’t this work?

Requirements?No Customized Hardware
All Open-Source Software
Extensible and Reproducible
Minimizes After-Installation Costs

Implementation, Part 1
Arduino Duemilanove: $30
disposable cell phone: $15
What is the simplest, least expensive way to accomplish this?

Implementation, Part 2Putting the pieces together….
Arduino enables buffers…
Phone dials DTMF tones…
DTMF transmitted over connected line…

Highlights…Not a replacement for maintenance of
solar power systems!
Working with Advanced Solar Technologies , Inc. (http://ast-solar.com/) on requirements, testing

Conclusion…
Realistic expectation is for working prototype
Progress slow but steady…
