Pulse Induction Metal Detector Sensor Clone PI-W ready universal metal detector

Description

Pulse induction metal detector
The module is a
universal pulse metal detector
on a microprocessor and uses Clone PI-Wcircuit and software solutions. Designed to search for
metal objects
in the soil, sand, walls, thick grass and others. The use of sensors of different sizes allows you to solve a
wide range of search tasks
.

Included Instructions in English.
Assembling and setting up a metal detector
Settings
are carried out away from industrial interference and large metal objects. If at this moment any metal object is near the sensor coil, the device, it is wrong. The power voltage is supplied to the contacts +VCC, 12V from the battery (in cases with the power supply, there may be interference that will lead to difficulty setting up the device). The search coil is connected to the contact L1, and the SP1 contact is 8 Ohms/0.5 watts. When feeding, the device is initiated by the device accompanied by blinking and characteristic sound. The SW3 SW6 buttons set the minimum barrier value. The tuning resistor R3 is rotated until the device begins to make sounds on its own, and then we turn the R3 a little so that the device is silent. At each position of the tuning resistor, we press the SW4 reset button and check the sensitivity. A
good result
by air can be considered
22-25 cm for five cents
. The setting of the metal detector can be considered finished. To look for a metal, we install a barrier in which the "instinct" of the device will be maximum with satisfactory stability. A well-tuned device does not give false works at 3-4 barrier LEDs
Making a search coil
For the manufacture of the search coil will need a
rigid non-metallic
mandrel Ø from 20 cm or more. The
larger the diameter
of the coil - the
higher the "intuition"
of the metal detector to large objects (for small and medium-sized objects the diameter of the coil is about 25 cm) 25-27 turns of enamelled copper winding enamelled wire ( Ø0.5 - 0.8mm).
The ends of the wire
to fix
and solder on the board to the contacts L1. In order to give a rigid form to the sensor, you can use impregnations that do
not conduct current
and do
not dissolve
the enamel insulation of the wire. For example, "TSAPON varnish", "Epoxy resin" or "polyurethane foam".
Complete with tested in
laboratory the assembled
metal detector
board has the english description which contains the circuit of the
metal detector
board.
To get the metal detector worked you have to do some soldering works with a cables, wires and connectors. Probably some instruments would be required.
Does not include
the coil, box, power connectors, wires or cables.
I am testing the
metal detector
before putting them in a shipping box. If you would not be satisfied with the
metal detector
then you ship it back and I refund your money.
