Magic Room: Device-free sensing of People using batteryless tags and machine learning

WINLAB Summer Internship 2024
Group Members: Xiang Meng & Aly Mustafa
Advisor: Aggelos Bletsas

Project Objective

Batteryless, ultra-low cost RFID tags can serve as additional ultra-low cost antennas; variations of the multipath propagation inside a room offers impressive information for estimating number of people and their tracks inside a room; WINLAB techniques, including machine learning, will be tested.

Weekly Progress

Week 1

​Week 1 Presentation
Progress: Started learning the TI Launchpad microcontroller, read the documentation, and spoke to an expert.

Week 2

​Week 2 Presentation
Progress: Learned how to use TI Launchpad MCU MSP-EXP430G2ET. Implemented an adjustable 200kHz-300kHz 50% duty cycle square wave output. Also implemented user input through digital input using the I/O pins. Attempted potentiometer user input, but did not successfully complete it.
