GreenLight - Automated Light, Automated Energy Savings

GreenLight is an integrated system which creates energy savings by automating indoor lighting. This project was done over the Spring of 2013 as part of a software development class (67-373) in Carnegie Mellon's Information Systems Department.

8. THE PROBLEM
9. THE PROBLEM Arti icial light provided by CFL bulbs is o en emitted in excess o what is necessary in an indoor space. This excess represents an entirely preventable waste o energy.
10. THE SOLUTION (OUR VISION STATEMENT)
12. THE SOLUTION Develop an in ormation system that automates arti icial light sources to enhance com ort and reduce energy consumption.

68. LESSONS LEARNED AN APPLE A DAY
69. LESSONS LEARNED PEOPLE A small team and highly-specialized roles were key to our success.
70. LESSONS LEARNED PROCESS The most success ul in ormation systems go beyond the standard web stack.
71. LESSONS LEARNED TECHNOLOGY Debugging code is hard.
72. LESSONS LEARNED TECHNOLOGY Debugging code is hard. Debugging electronics is harder.
73. LESSONS LEARNED TECHNOLOGY Debugging code is hard. Debugging electronics is harder. Debugging both at the same time is a nightmare.
