Main chip: LM393, 3144 Hall sensor
Working voltage: DC 5V
Size: 2.7 cm x 1.4cm
Interface description (4-wire system):
1 VCC external 5V voltage
2 GND external GND
3 DO small board digital output interface (0 and 1)
1. Has a power indicator and signal output indication.
2. Single signal output.
3. The module has no trigger and the output is low; the module has a trigger and the output is high.
4. Sensitivity is adjustable (fine adjustment).
5. There is a signal output when there is magnetic field cutting.
6. The output of the circuit board can be directly connected to the single-chip microcomputer or our relay module, buzzer module and so on.
7. Can be used for motor speed/position detection and other occasions.
