The hall effect sensor is just like switch as it works on hall effect principle so, it is more sensitive to magnetic flux and suitable for harsh environment because of semiconductor type casing and no glass encapsulation. This Ky003 Hall Effect/Magnetic Sensor module has 3144EUA-S hall effect sensor, it changes its state if one pole of magnet comes near it which can be easily read by any Digital GPIO pin on the Microcontroller board. This is ideal for commercial, consumer and industrial applications like measuring the RPM of the wheel, position sensor for machining tools, positional feedback for control systems, detecting the poles of magnets in BLDC Motors, magnetic alarm doors etc. You can use digital Read with delay or can use attach interrupt function in Arduino which read if there is any change in state at the digital pin the attach interrupt is enabled.
