2025 ECE 412/413 COATL-RADAR PROJECT
Green Coffee Bean Moisture Content Detection Using 60GHz Radar Module
Chris Kane-Pardy
Kamal Smith
Henry Sanders
Wallace Mckenzie
Acconeer Provided File for Flashing Firmware to New XE125 EVK Radar Module
Initial Test Programs to Interface with Acconeer A121 Exploration Tool Through Python
After Deciding Against Calculating Permittivity, We Created These Programs, Which Attempted to Mitigate Inconsistencies in Results due to Bean Geometries
Collected Datasets for Use in Machine Learning
Original Test Programs, Which Aimed to Determined Moisture Content by First Calculating Permittivity from Acconeer "IQ" Data
Final Program Version Which Utilizes Several Averages and Captures the Entire Waveform of the IQ Data Scan
Final Program Version With Modified Settings Aimed at using Ground Roasted Coffee
Original Exploratory Machine Learning Programs
3 Separate Versions of the Base Machine Learning Program (Chris, Kamal, & Henry), Which We Used to Test and Compare Accuracy Across Different Settings
The Final Version of Our Machine Learning Program
Outdated Programs for Interfacing ESP32 to Stepper Motor Using I2C for Bean Rotation
