Metal Sniffer: Metal Detector for Android

By Morning Rain Free

Developer's Description

=== Metal Sniffer: Metal Detector ===

Metal Sniffer is a portable metal detector. By detecting nearby electromagnetic fields using the phone's built-in magnetometer/compass, you can locate nearby metal and magnets. You can also use it to find metallic studs and wiring behind walls. Depending on your phone, you can use it to detect metals up to 30cm away, and magnets from far, far away! Note that household equipment like TVs, and computers or even your phone case can affect readings.

Readings are separated per dimension, and is given in the unit of your choice (Tesla, Gauss, or Gamma), and combined to give a scalar reading. You can set a threshold at which the phone will vibrate when a critical reading has been reached.

You can also see a reading trend through the graph, or switch to the compass mode to find the direction at which the current is coming from! You can also record the readings to a .csv file for tracking or research.

===How to use this app?===

Very simple, just move the app around and read the measurements, if the magnetic field readings go over a critical level, the phone will vibrate, meaning a ferromagnetic material is nearby.

If the readings aren't getting updated, make sure your phone is equipped with a magnetometer.

If the readings seems to be off, it means that your sensors needs to be re-calibrated, click the re-calibration button (refresh icon) for instructions.
