How It Works / কীভাবে কাজ করে
This kit works by using a coil-based detection circuit. When a metal object comes near the coil area, the circuit condition changes. The board then gives an output indication through buzzer or LED.
এই kit-এ coil-based detection circuit ব্যবহার করা হয়। Metal object coil-এর কাছে এলে circuit-এর signal change হয় এবং buzzer/LED-এর মাধ্যমে indication পাওয়া যায়।
It is designed for learning and demonstration, not for professional or deep underground metal detection.
Assembly Guide / অ্যাসেম্বলি গাইড
- Identify all components from the kit.
- Insert low-height components first, such as resistors.
- Then insert capacitors, transistors, LED and other components.
- Check component polarity carefully.
- Solder all pins properly on the PCB.
- Cut extra leads after soldering.
- Connect suitable DC power supply/battery according to the circuit requirement.
- Adjust the potentiometer for sensitivity tuning.
- Bring a metal object near the coil area and test the response.
Important Soldering Notes / গুরুত্বপূর্ণ সোল্ডারিং নোট
⚠️ Check resistor values before soldering.
⚠️ LED, electrolytic capacitor, transistor and diode polarity must be correct.
⚠️ Avoid solder bridge between PCB pads.
⚠️ Do not overheat small components during soldering.
⚠️ Use proper DC voltage according to the kit requirement.
⚠️ Recheck all connections before powering the circuit.
Detection Performance Note
Detection distance depends on:
• Metal object size
• Metal type
• Power supply voltage
• Circuit tuning
• Potentiometer adjustment
• Soldering quality
• Environmental electrical noise
Large metal objects are usually easier to detect than very small objects.
