Is it possible to find wiring in the wall using a smartphone: an experiment

Hidden wiring in the wall can be found in several well-known ways: with a special device; indicator screwdriver with high sensitivity for contactless detection of wiring; a radio receiver and a hearing aid. The last two methods, of course, raise doubts, but they say that they work. Now there are applications for smartphones, which, according to the developers, can easily detect hidden wiring or a metal pipe in the wall. Is this really so, the participant of our portal Andrey will tell.

Encouraging information

Somehow I had the urge to drill a wall in the apartment for a TV bracket. The location of the wiring is unknown and therefore it was necessary to determine if I would accidentally fall into a live wire. There is nothing at hand for indication, but I don't want to go to the hardware store for the device.

I decided to see what people write on the Internet about detecting wires in the wall. I enter a request - useless options pop up. Useless, because the radio has not been at home for fifteen years, and I don't use a hearing aid.

And suddenly I come across a modern life hack. It turns out that there are already apps for smartphones that can act as an indicator for finding wiring, a metal detector and a hertz meter. "Well done, now you don't have to suffer!" - I thought and immediately downloaded this application.

What happened in practice

The first app downloaded was not in Russian. But this is not a problem, you can figure it out. In anticipation of victory, he pressed the "search for wiring" button and brought it to the wall. The arrow of the device has not deviated anywhere. Well, I guess there is no wiring here. How does it work? It became interesting.

I bring the phone to the socket, the arrow jerked slightly and something squeaked. He began to drive around the outlet - silence. He does not see the wiring. I bring the phone to the extension cord. All the same - he does not see the wires as his own ears! I carry my smartphone to the dashboard, I place it right between the wires and NOTHING!

By the way, my phone is new. The model is not the cheapest: Samsung Galaxy A52. Well, I think the application is not important, although I downloaded the software with the highest rating. I downloaded one more - it does not work. Then one more thing - the same result! Tried five different "wire finders" for phones and none of them work! They can't even see live wires, let alone hidden wiring.

I decided to try on Hertz. It turns out that I have 32 Hz in the center of the room, and all 80 Hz near the wire! Surprised so surprised!

In my opinion, these applications cannot be trusted. All they do regularly is show ads every 3 minutes. This is where their "useful" functions end.
