Build a WiFi Network Scanner and Channel Analyzer with ESP32 and TFT Display

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn an ESP32 into a professional-grade WiFi signal analyzer. This kit guides you through building a real-time scanner that visualizes every network nearby, showing signal strength and channel interference on a crisp 1.8-inch TFT display. Ideal for learning wireless fundamentals or diagnosing your home or college network.

What You'll Build

A portable WiFi scanner that detects all access points, dynamically plots their SSIDs against Received Signal Strength Indicator (RSSI) as a bar chart, and overlays a channel utilization map to reveal congestion. You'll have a handheld tool to survey campus or office networks instantly.

What You'll Learn

• Program an ESP32 to scan WiFi networks and parse 802.11 management frames
• Interface an ST7735 TFT display using SPI for real-time graphics
• Convert RSSI values to meaningful visual bar charts and color-coded channel maps
• Understand Wi-Fi channel overlap, co-channel interference, and signal propagation
