Detects Wi-Fi deauthentication attacks using an ESP8266 microcontroller by monitoring for malicious management frames.
DeauthDetector is an open-source hardware project that uses an ESP8266 microcontroller to detect Wi-Fi deauthentication attacks. It monitors wireless traffic for malicious deauthentication or disassociation frames and provides a visual alert via an LED. This helps users identify when their Wi-Fi network is being targeted by a common type of wireless disruption attack.
IoT enthusiasts, hardware tinkerers, and individuals interested in wireless network security who want a low-cost, DIY solution for monitoring Wi-Fi attacks.
It offers a simple, affordable, and customizable alternative to commercial wireless security tools, leveraging widely available ESP8266 hardware and open-source code for transparency and adaptability.

Based on the ESP8266 microcontroller, it leverages inexpensive and widely available components, making it accessible for hobbyists and educational projects, as highlighted in the features.
It specifically monitors for deauthentication and disassociation frames, providing clear, immediate alerts via an LED, which is explicitly stated in the README as its core functionality.
Users can adjust scanning channels, packet rate thresholds, and LED behavior by editing the Arduino sketch, as demonstrated in the configuration snippet in the installation guide.
The project is entirely open-source, allowing for code auditing, modifications, and learning, which aligns with its philosophy of accessibility and simplicity.
It only provides a local LED alert with no built-in way to send logs or alerts over the network, limiting its usefulness for proactive security monitoring.
All changes require editing and re-uploading the Arduino code, as there's no web interface or runtime configuration, making it less user-friendly for quick adjustments.
The ESP8266 hardware restricts detection to 2.4GHz Wi-Fi channels, so it cannot detect deauthentication attacks on modern 5GHz networks.
