Have you ever wished you could see in the RF part of the radio spectrum? While such a skill would probably make it hard to get a good night’s rest, it would at least allow you to instantly see dead spots in your WiFi coverage. Not a bad tradeoff.
Unwilling to go full [Geordi La Forge] to be able to visualize RF, [Ken Kawamoto] built the next best thing – an augmented-reality RF signal strength app for his smartphone. Built to aid in the repositioning of his router in the post-holiday cleanup, the app uses the Android ARCore framework to figure out where in the house the phone is and overlays a color-coded sphere representing sensor data onto the current camera image. The spheres persist in 3D space, leaving a trail of virtual breadcrumbs that map out the sensor data as you warwalk the house. The app also lets you map Bluetooth and LTE coverage, but RF isn’t its only input: if your phone is properly equipped, magnetic fields and barometric pressure can also be AR mapped. We found the Bluetooth demo in the video below particularly interesting; it’s amazing how much the signal is attenuated by a double layer of aluminum foil. [Ken] even came up with an Arduino with a gas sensor that talks to the phone and maps the atmosphere around the kitchen stove.
The app is called AR Sensor and is available on the Play Store, but you’ll need at least Android 8.0 to play. If your phone is behind the times like ours, you might have to settle for mapping your RF world the hard way.

This is a fantastic idea. No doubt could be improved, but using AR with the rss, as a engineer myself is an excellent premise. Great work!
“Have you ever wished you could see in the RF part of the radio spectrum?”
I generally used a spectrum analyzer to do that.
exactly. toys may inspire imagination but.. for field strength of a wireless signal, why not….
maybe the pretty pictures will inspire number lust.
One would be Geordi La Forge if one could do that. I seem to remember it gave him headaches.
This is cool, down loaded to my Samsung S8. Going to play with it tonight.
Woah, this is cool!
Will be getting it running on my Pixel ASAP!
Was able to diagnose a WIFI performance issue within 10 minutes of seeing this headline. Thanks! The magnetism mode seems to be bugged, takes samples at a very fast rate and the results disappear quickly.
Doesn’t work on my Note 9 in pie. My work Moto Force touch isn’t compatible either… :-(
Why don’t we have an edit here yet?? Note 8 in pie…
Google tells me it won’t go on my LG but it seems to satisfy the specs quoted. More investigation or a new phone it seems.
Be sure to add the ARCore first or it will not load. Maybe that is your issue.
Thansk for that. It may have helped to mention that somewhere but no, that aint compatible either.
Most useful looking thing I have seen for Android for some time, just my luck.
This is WAY COOL! Works just fine om my Note 8, really fun mapping out the office WiFi. Great idea!
There is an older uglier App for iOS called ColdSpotting (sounds like a movie title) that does the same same thing. It came out earlier this year.
Besides have the cool factor I learned about ARCore, great possibilities. Also look at his posting outside of HAD. shows hooking up an Arduino to his phone the Arduino had a sensor and mapping that sensor. Opens to lots of possibilities.
This looks so cool, I’ll try this out. Just curious, does this work in a Daydream View headset?
The ARCore shows a list of suitable devices.
Oh for an edit.
Don’t Work on Asus Zenphone Max Pro with Android 8.1.0 …
