2.4 GHz scanner based on ESP32 Wifi module

[AlekseiOL]

Hello everyone

I'm trying to implement RF scanner for 2.4GHz. There are a lot of examples how to scan well known 16 Wifi channels with ESP but is it possible to scan non-wifi 2.4 frequencies (like RF toys controllers, microwave ovens)? I've played with NRF24 which can scan 128 channels but it doesn't fit because it cannot measure signal strength properly (it only says if the signal is higher than 64dB). I suspect Cywm6935 chip can do something like this but these chips are too expensive and out of production...
Is it possible to solve that task with ESP32? Thanks for any information

The RCWL-0516 is an inexpensive proximity sensor that works using microwaves and Doppler Radar. It can be used on its own or with an Arduino.

Unfortunately RCWL-0516 won't work - it uses different frequency range and this range is not configurable (as far as I've could read) But the overall idea was great
