Hall Effect sensor KY-003 Magnetic Sensor DC 5V 3144EUA-S Arduino PIC AVR Smart Cars
The KY-003 Module is a 3144EUA-S Hall Magnetic Sensor Switch that turns itself ON or OFF in the presence of a magnetic field. This module is compatible with a microcontroller like Arduino, Raspberry Pi and ESP32. Module KY-003 is capable of measuring wheel RPM, detecting the poles of magnets in BLDC Motors, a position sensor for machining tools, positional feedback for control systems, etc.
Non-contact switch.
