About this project
Build a wideband RF spectrum analyzer using ESP32, AD8307 logarithmic detector, and Telegram Bot interface. Scan 50MHz-2.4GHz spectrum, detect Wi-Fi channels, identify interference sources, and measure signal strength in dBm. Send /scan command to bot, receive waterfall plot showing frequency vs. time vs. amplitude. Features automatic peak detection, channel power measurement, harmonic analysis, and CSV export for GNU Radio post-processing. Perfect for RF debugging, antenna tuning, EMI compliance testing, and amateur radio spectrum monitoring.
