James46717 just shared a new project: "Wifi Sniffer"
This project started because I wanted to know the signal strength of the Wifi in various places around my house. I had set up a Pi Zero as a simple watering system controller. It would switch a solenoid on and off based on a 7 day schedule; which I could setup via a web page from my desktop PC. The place I chose for the Pi Zero was not the best as it was on the border of stable Wifi (-79dBm). Having a portable Pi Zero that would display the signal strength of wherever it was placed, seem like a good idea.
