There exists an urgent need on the market for a low-cost, low-power-consumption, accurate wireless level device. The
current levels available to people in need today only fulfill some of the requirements, causing people trouble and making them
inefficient when performing their jobs. The device that we propose to create will be inexpensive, but also provides a handheld
receiver that will allow the user to monitor the level from distance away. We choose to focus on implementing a device that will
improve work quality for workers.

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.
