30-11-2020· Very Low Frequency (VLF) Converter Circuit. The circuit explained below can be used for detecting and converting the very low radio frequencies or VLF in the atmosphere to audible sound. A huge number of general-coverage shortwave receivers start with the AM-broadcast band and rise in frequency to around 10 meters, or 30 MHz.
We can use a grid of thin metal to shield the sensor, like the one used to make anti-mosquito grid for windows. This material is readily available at hardware stores. Before being installed the grid must be isolated: I got the insulation by mounting the moschito grid inside of two larger sheets of nylon bubble.

06-05-2021· Making a VLF metal detector? system July 17, 2013, 8:11pm #1. I've been thinking it might be interesting to try to make a metal detector using an Arduino, and it seems like a VLF sensor would be the best way to go; outputting signal at ~10KHz should be feasible. My question is, what would be the best way to go about making the actual sensor?

In the air, GEM's VLF is used with its airborne optically pumped magnetometer and gradiometer systems with 10 Hz sampling. Two stations of data can be acquired simultaneously – maximizing the efficiency of the survey process. Other advantages of GEM's airborne VLF include air-core sensors in contrast to a ferrite core used by competitors.
