This module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal. It can be used in many applications such as RPM sensor (for counting the number of shaft revolutions), Robot speed and distance measurements, door switch and robot arm position sensor. Generally, it can be used for any magnetic field detection.
- S49E hall sensor
- Features wide range voltage comparator LM393
- Adjustable sensitivity (potentiometer)
- Signal output indicator
- Analog / Digital output
Connect board’s power line (+) and ground (G) to 5V and GND respectively. Connect the digital signal (D0) to pin 3 on the Arduino and the board’s analog signal (A0) to pin A0 on the Arduino.
