Description SPESIFIKASI : Size: 2.7 cm * 1.4mm Main chip: LM393, 3144 Hall sensor Working voltage: DC 5V n nModule interface description (4-wire system) VCC external 5V voltage n2 GND External GND n3 DO small board digital output interface (0 and 1) With power indicator and signal output indication. Single signal output. The module has no trigger and outputs low level; the module has trigger and outputs high level. Adjustable sensitivity (fine adjustment). Signal output when there is magnetic field cutting. The output switching value of the circuit board can be directly connected to the single-chip computer or our relay module, buzzer module, etc. It can be used in motor speed measurement / position detection and other occasions.
