Dec 05, 2018· Simple metal detector circuit is Implemented by employing IC CS209A from cherry semiconductor (now its on semiconductor), the CS209A is a bipolar monolithic integrated circuit for use in metal detector applications and Inductive proximity sensing applications.

Figure 3: The PWM circuit block. At the heart of the circuit is a simple 555 timer set to produce a PWM signal at a frequency of 615Hz and a duty cycle of 96%. The values for R1, R2 and C1, control the 555. The output of the 555 timer, pin 3, is driven through R3 to the base of Q1, a 2N3906 PNP transistor.

Homemade metal detector 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 meters. Between amateur radio using designs of special interests that help in detecting metal objects hidden in the ground.

The inductive proximity sensor circuit is used for detecting the metal objects and the circuit doesn't detect any objects other than metals. The above proximity sensor circuit diagram represents the field produced by the coil, which is generated by providing a power supply. Whenever, this field is disturbed by detecting any metal object (as a metal object enters this field), then an eddy current will be generated .

EXP5000 is visible on the ground floor of the German import detector can detect 30 meters. The detector using the latest technology, through the provision of video glasses buried objects such as boxes, water pipes, metal, and severe tooth decay and become visible under the court surface.
