A portable Wi-Fi analyzer built with an ESP32-S2 Mini and OLED display. It scans nearby Wi-Fi networks and displays SSID, signal strength, channel and security type.
Ship #1
Pending review
The first version of my ESP32 Portable WiFi Analyzer is complete.
The device can:
- Scan Wi-Fi networks
- Display signal strength
- Show channels
- Detect security type
- Switch between networks
Future improvements:
- Signal graphs
- Web interface
I added a button for browsing detected Wi-Fi networks.
The ESP32-S2 Mini built-in BOOT button is used as the navigation button.
I also added button debounce to prevent multiple inputs from a single press. I improved the project structure and documentation.
Changes:
- Added GitHub repository structure
- Added README
- Added MIT license
- Improved code comments
- Added hardware documentation
The project is now easier for others to build.
Today I created the first working version of the Wi-Fi analyzer.
The ESP32-S2 Mini can now scan nearby networks and display them on the OLED screen.
I connected:
- ESP32-S2 Mini
- SSD1306 OLED display
The biggest challenge was getting the OLED communication working correctly.
I started a new hardware project for Hack Club Stardance.
The goal is to create a small portable Wi-Fi analyzer using an ESP32-S2 Mini and an OLED display.
The device should be able to scan nearby Wi-Fi networks and display:
- SSID
- signal strength
- Wi-Fi channel
- security type
I chose this project because I am interested in electronics, ESP32 development and wireless communication.
