HS-S72P Metal Detector Sensor

1. Introduction

Another set of coils (receiving coil) detects changes in the magnetic field (such as flux, frequency, or phase shift), converts the signal into an electrical signal, and then amplifies and processes it to trigger an alarm or output the detection result.

10, Test conclusion

Arduino UNO test results:

After connecting the device, upload the above program to the UNO-R3 PRO development board and then power on.Place a metal object on the detection plate. The LED module will light up when it detects metal, otherwise it will turn off.
