Wi-Fi! It’s in all places, and but you may’t actually see it, by advantage of the expertise counting on the transmission of electromagnetic waves exterior the visible spectrum. By no means thoughts, although, as a result of you may all the time construct your self a Wi-Fi analyzer to get some perception into your radio environment, as demonstrated by [moononournation].
The core of the construct is the ESP32-C5. The favored microcontroller is well-equipped for this activity with its onboard dual-band Wi-Fi {hardware}, even when the inventory antenna on most devboards is a bit of underwhelming. [moononournation] has paired this with a small rectangular LCD display working the ILI9341 controller. The graphical interface is drawn with the help of the Arduino_GFX library. It reveals a graph of entry factors detected within the instant space, in addition to which channels they’re utilizing and their obvious sign power.
When you’re simply making an attempt to get a primary learn on the Wi-Fi atmosphere in a given locale, a device like this may show fairly helpful. In case your needs are extra superior, you may leap as much as tinkering on the planet of software program outlined radio. Video after the break.
