Magnetic induction sensor detection circuit with single-path and multi-path output

The utility model discloses a single-path and multi-path output magnetic induction sensor detection circuit comprising a Hall element (U1) used for sensing an external magnetic field; a power supply element (Q1, R1) for supplying electrical energy to the Hall element (U1); a detection element (Q2) that detects the output voltage of the first output terminal of the Hall element (U1); the control unit (RL) is used for controlling the voltage value output by the detection circuit; according to the magnetic induction sensor detection circuit with single-path output, only two wires need to be provided for outputting high-low level signals to be received by the single chip microcomputer, the circuit structure is simple, the magnets can be stably induced to be close to or away from each other tooutput the high-low level signals, the high-low level signals can be directly recognized by the single chip microcomputer, no signal carding circuit needs to be additionally arranged, and the cost isfurther reduced. 本实用新型公开了一
