Instructions

1. Power Supply:

   • Connect the VCC pin to the power supply within the operating voltage range (4.5V to 24V DC).
   • Connect the GND pin to the ground of the power supply.

2. Output Connection:

   • The output is an open collector, so connect a pull-up resistor between the output pin (OUT) and VCC.
   • The typical value for the pull-up resistor is 1k惟 to 10k惟, depending on the application.

3. Sensitivity Adjustment:

   • The sensitivity of the sensor can be adjusted using the potentiometer provided on the sensor module.
   • Turn the potentiometer clockwise to increase sensitivity and counterclockwise to decrease sensitivity.

4. Installation:

   • Mount the sensor in a location where it will not be exposed to temperatures outside the operating range.
   • Ensure that the sensor is aligned with the magnetic field source for optimal performance.

5. Testing:

   • Apply a magnetic field near the sensor to test its operation.
   • The output pin (OUT) will go low when the magnetic field strength exceeds the set sensitivity threshold.

6. Handling:

   • Handle the sensor with care to avoid damage from static electricity or physical stress.
   • Store the sensor in a dry, cool place when not in use.

7. Troubleshooting:

   • If the sensor does not respond to a magnetic field, check the power supply connections and the pull-up resistor.
   • Ensure that the magnetic field strength is within the detectable range of the sensor.
   • Adjust the sensitivity if necessary.
