Purpose of this Metal Detector Principle:
Example 1: If you want to detect whether there is a car passing by on a certain road, because the height of the car chassis is 0.5 meters or more from the road, and the cement will be buried at a depth of 5-10CM, so you can bury a coil with a diameter of 1 meter on the ground. Stable, accurate and reliable detection of whether there is a car on it is of great practical value in highway traffic statistics and parking lot prohibited area statistics.
Example 2: A sensor is required on each floor of the elevator controller to detect whether the elevator has reached the stop position. If a mechanical travel switch is used, there will be life and reliability factors; if a photocoupler is used, there will be a long time Dust deposition failure; therefore, the only way is to install a metal detector to determine whether the circuit is on or off based on the presence or absence of metal. This will have high practical value in many equipment and machines.
