Hi,
I want to design a dual channel inductive-loop vehicle detector, I haven't found enough circuit diagrams online.
And the products on Aliexpress are either connected to relays or have factory fabrication where I can't get signal output to read by Arduino board.
I learned the basic principle of designing inductive-loop circuit, which is:
1. Use 18 AWG wire.
2. Do the turns until I get inductivity by the LCR from 50-220uH or similar values.
3. Run the circuit by a certain voltage.
4. The frequency should be 120kHz.
5. Then I can measure the difference in the voltage, by using a current sensor.
But is the circuit that easy ?
