metal detection using FLC 100 sensor

[Hesamavr]

Is it possible that FLC 100 sensor be used for metal detection, coin haunting etc ...? if yes, how would be its reaction in front of small or big metal objects and in what detection ranges?

What it is?

What it is?

it is a sensor which capable of detecting very small magnetic changes. Google it a bit. it is expensive since I want to know if it is suitable for this purpose before purchasing it.

Ohh ok the only flc circuit i was familiar with were the little transistor flc240 (fire lighter circuit) electronic scr/diac switches

This is fluxgate sensor. Yes it can be use, but only for Fe-magnetic object.

It is possible to detect metal coins with the FLC 100 sensor. For more details, see the following link: http://aircconline.com/sipij/V7N6/7616sipij01.pdf

i see 10 pcs of flc100. ie the price of just fls's is 10x100 1000 euro. good project for a son of Rockefeller.

Much cheaper are FG-3 sensors from https://www.fgsensors.com/
If you need analog input you can simply use frequency to analog converter chip. But I think frequency is more robust.

we need winter project with two sensors FG-3 connected to Arduiono and this Arduino connected to microUSB socket of an iphone.
we need see 3D color image on iphone.

Tend to agree.
I made also an FLC100 version of my gradiometer and am in good position to compare.
Voltage range at FLC100 is too narrow to be processed in bare 10bits at Atmega328P.
Either special "driver" (that's how some people named it) circuitry is necessary... either to use better ADC.
So i added 24-bit ADC and situation significantly improved.
But that's quite another situation; more "ironmongery" = different story.
For as straightforward as possible application; FG(M)-3 is better choice. Most certainly.
