Ivconic's Negative Ion Detector circuit

2006/3/16The ordinary metal detector is detecting an electromagnetic wave that is expected to arrive at a very specific time (PI), or a deformity in the elelctromagnec field of the search coil (non-PI). This is not the same as trying to detect static electric fields 4 feet above the ground. Get price

Metal detector circuit using IC 555

This metal detector circuit uses IC 555 chip along with an inductor was to build a cheap and simple metal detector at our home. WORKING: The inductor of 10mh in the above circuit serves the purpose of metal detection and 555 serves the multivibrator section of the above circuit. Get price

2020/2/29A suggestion. Do it like traffic lights detect cars. Wind a coil ( 10-100 turns? of wire round the flap, use it as part of the resonant circuit of an L-C oscillator, and measure the frequency. Say a few 10's of kHz. Any nearby metal object should alter it. Alan Get price

Metal Detector Circuit using Single Transistor

2018/1/10The post explains a simple one transistor metal detector circuit which is very sensitive and and can detect any metal from a significant distance. We are going to begin the topic assuming situations have settled following a few cycles and the voltage within the base of the transistor is steady (fixed by the retaining or resisting the activity of the capacitor 10n).
