An adaptive lighting system that responds to the environment in setting the brightness and color temperature of an LED light, using occupancy detection and current light levels. A sensor unit will be set on a table, and wirelessly transmit to a microcontroller that controls an RGB LED array. This work will improve upon the project "Color Adaptive Interior Lighting" and "Adaptive Solid State Lighting" from fall 2011 by utilizing a color sensor, CCT setpoints, an occupancy sensor, and will be adaptable to multiple lighting sources. We hope that this system will lower overall power usage, and lead to a more pleasing lighting experience.

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.

Description:

We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
