# JC4827W543 Wifi Analyzer







## Youtube Tutorial

[](https://youtu.be/mnOzfRFQJIM)

## Project Description

This project turns the JC4827W543 (ESP32-S3) development board into a standalone 2.4 GHz WiFi analyzer. It performs continuous WiFi scans and renders a live channel graph on the onboard display so you can quickly see network density, signal strength, and likely lower-noise channels for better WiFi planning.

## Features

- Live 2.4 GHz WiFi scanning and visualization on channels 1-14

- Channel-by-channel RSSI graph with color-coded channel traces

- Strongest network label per channel (SSID/BSSID + RSSI)

- Open network indicator (`*`) when encryption is not enabled

- Automatic low-noise channel suggestion (channels 1-11)

- Per-channel access point count shown under each channel

- Periodic refresh loop (default scan interval: 3 seconds)
