How I Built My Packet Monitor

is there traffic on your network when you are not using it? Or what information does this traffic have, the answer to these needs will all be met with an interesting and practical device called Packet Monitor? It is a computer program or hardware, which can record the traffic that passes through the computer network or part of the network. When data flows through the network. Analyzers can store each packet and decrypt raw packet data if needed. In this project, we will build a PacketMonitor device with an ESP8266 board. We will receive the traffic in each channel and then display it graphically in graphs using the OLED display.

How PacketMonitor work?!

In this project, the traffic values ​​in the channel specified from 1 to 14 are received with the help of ESP8266 WiFi board and Wemos boot board, and in the Oled display, which is driven by the i2c interface, graphically in the form of incoming traffic at any time. is shown. We will also be notified if there is a malfunction or deauth attack on the channel in question. We will also be able to change the channel number being analyzed using the key attached to pin D3 on the Wemos board.
