In this project, we will demonstrate how to build a simple metal detector circuit. The device we then build will function as a metal detector that can scout out metal objects, such as coins, nails, keys such as car keys you may not be able to find, and even gold if you're looking for in a beach (though this one may not have industrial strength).
The following image shows the circuit diagram for the metal detector circuit. Components Required . 1 x TDA0161 Proximity Detector IC; 2 x 47nF Capacitors (Ceramic Capacitor code 473) 1 x 1 KΩ Resistor (1/4 Watt) 1 x 330 Ω Resistor (1/4 Watt) 1 x 100 Ω Resistor (1/4 Watt) 1 x 5 KΩ Potentiometer; 1 x 2N2222A (NPN Transistor) 1 x 5V Buzzer; Coil (copper wire of 26 – 30 AWG is taken and it
03.09.2020· The post discuses 4 simple motion detector circuits using op amp and transistor. We also discuss the pinout details of the standard passive infrared (PIR) sensor RE200B. We will Learn: How to use a PIR sensor device to Detect human body infrared. How to use a PIR module as a Security Burglar Alarm Circuit; How to use a PIR to switch ON lights when a human presence is detected. How to
Gold Detector Schematic Penulis schematic diagram. Tags. misc. Here the very simple and easy build gold detector circuit. The circuit capable to sense gold or metal or coins from a distance of about 20cm, depending on the size of the object to detect. The circuit oscillates at about 140kHz and a harmonic of this frequency is detected by an AM radio. You can simply tune the radio receiver until

So here in this Arduino Metal Detector Project, we have to find inductance of the coil to detect metals. So to do this we have used LR circuit (Resistor-Inductor Circuit) that we already mentioned. Here in this circuit, we have used a coil having around 20 turns or winding with a 10cm diameter. We have used an empty tape roll and wind the wire around it to make the coil. Circuit Diagram: We
Circuit diagram for a Homemade metal detector, and a description of the design of the detector base and precious metals, able to detect objects at a depth of 2.3 meters. Between amateur radio using designs of special interests that help in detecting metal objects hidden in the ground.
This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket radio. This is nothing but a Colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. First, the radio and the circuit are placed close. Then the radio is tuned so that there is no sound from the

Circuit Diagram and Working. The figure shows the circuit diagram of metal detector. The 555 IC timer here acts as a square wave generator and it generate pulses with frequencies audible to human. The capacitor between pin2 and pin1 should not be changed as it is need to generate audible frequencies. In the circuit there is an RLC circuit formed by 47K resistor, 2.2µF capacitor, and 150turn
A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881. They have been utilised to localise a myriad of

Metal Detector circuit diagram. As shown, the circuit oscillates at around 230kHz. One may also experiment with the frequency by changing the value of C1. A Faraday shield may be added to reduce ground effect and capacitive coupling, and this is wired to 0V. Metal detector video with a funny song . Since the inductor resists rapid changes voltage, the charging of C1 is slightly delayed as the
