Detector (Signal Detector)
Wideband presence detector
What it does
SimpleThis watches a wide range of frequencies and lights up when there's a strong radio signal nearby, keeping a little history of what it noticed. People use it to check whether something is quietly transmitting in a room.
It's like a smoke detector, but for radio energy — walk around and it tells you where things are 'hot'.
How it works
SimpleIt sweeps across many frequencies and compares what it hears to a threshold you set. If something is louder than that threshold, it flags it and remembers it, so you can tell when and where a strong signal showed up as you move around.
How to use it, step by step
Simple- Open the 'Detector' app.
- Set how wide a range to watch and how strong a signal must be to flag.
- Walk around a room.
- Watch it light up near strong signals and check the history.
Examples
Check a room for an unexpectedly strong near-field transmitter.
Track down which device is radiating by watching where the detector fires as you move.
Confirm whether a suspected transmitter is active before digging in with a full sweep.
Tips & things to try
- It sits between Level (one frequency) and Looking Glass (full detail) — great for a fast wide check.
- Set the threshold to your environment: too low flags everything, too high misses weak emitters.
- Use it to find *where* to look, then switch to Looking Glass to see *what* it is.
