Low-Cost SDR Spectrum Monitoring Station
RTL-SDR and GNU Radio radio frequency waterfall analyzer detecting unauthorized RF transmissions across 24MHz - 1.7GHz.
Project Overview
Computes Fast Fourier Transform (FFT) spectrum sweeps, logs signal power levels, classifies analog/digital modulation schemes (AM, FM, ASK, FSK), and alerts operators to frequency channel occupancy. ### Practical Student Engineering Solution Fully functional hardware demonstration prototype equipped with dedicated microcontrollers, precision sensors, actuators, and an interactive cloud/mobile telemetry dashboard. ### Key Learning Outcomes - Embedded C / MicroPython firmware architecture and sensor interfacing - IoT telemetry protocols (MQTT / HTTP / BLE / LoRaWAN) - Power regulation, hardware debugging, and PCB design principles - Comprehensive technical documentation aligned with IEEE academic standards
Modern commercial and industrial infrastructure requires automated, real-time sensing and telemetry. Conventional manual monitoring suffers from high latency, human error, and lack of predictive fault visibility for Low-Cost SDR Spectrum Monitoring Station.
A turnkey engineering prototype integrating high-precision sensor modules, dedicated microcontroller unit, and cloud telemetry protocols to automate measurement, trigger alert thresholds, and provide remote dashboard control.
