If you want to get started sniffing Wi-Fi networks, you usually need to start with a wireless network adapter. But thanks to a Wi-Fi sniffing library written in Arduino and the ultra-cheap ESP8266 chip, you might not need one. For less than $10 in electronics, you can build a tiny Arduino Wi-Fi sniffer that saves Wireshark-compatible PCAP files and fits anywhere.

Sniffing Wi-Fi packets allows you to learn a lot about the wireless landscape of an area. Even without the Wi-Fi password, you can learn about the types of devices that are nearby, which devices are connected to which networks, and more information that can be useful to a hacker. But to get started doing this, you'll typically need to invest in a wireless network adapter that gives you more control than the average consumer adapter.


While there is much debate about which wireless network adapter is the best, it can get expensive trying out which one is right for you. If some simple sniffing is all you're looking for, then it turns out a cheap, easy-to-program microcontroller might work just fine instead.
