Zusammenfassung:The present teaching relates to a magnetic sensor comprising an input port to be connected to an external power supply, a magnetic field detecting circuit configured to generate a magnet detection signal, an output control circuit configured to control operation of the magnetic sensor in response to the magnet detection signal, and an output port. The magnetic field detecting circuit includes a magnetic sensing element configured to detect an external magnetic field and output a detection signal, a signal processing element configured to amplify the detection signal and removing interference from the detection signal to generate processed detection signal, and an analog-digital conversion element configured to convert the processed detection signal into a magnet detection signal, and the output control circuit is configured to control the magnetic sensor to operate in at least one of a first state and a second state responsive to at least the magnet detection signal.
