Linear Hall Magnetic Module that detects any magnets (can define the S , N poles) so you can use it also as a module to measure the speed of rotation magnet.
This Module detects the presence of a magnetic field supplying at the output a voltage related to the intensity and the orientation at the same time.
Very easy to connect to your microcontroller or your Arduino board (For Arduino simple code - check the datasheet for this item)
Features:
- Adjustable sensitivity (potentiometer)
- Voltage comparator LM393
- LED Signal output indicator
- Analog and digital output
- Based on hall sensor # 49E
