Instructions for Use

1. Power Supply:

   • Connect the VCC pin to a power supply between 4.5V and 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 (typically 4.7kΩ to 10kΩ) between the output pin (OUT) and the positive supply voltage (VCC).
   • Connect the OUT pin to the input of your microcontroller or other device.

3. Magnetic Field Detection:

   • Place a magnet near the sensor to trigger the output. The sensor will switch its output state when the magnetic field strength exceeds the specified sensitivity levels (Bop and Brp).

4. Mounting:

   • Ensure the sensor is mounted in a location where it can detect the magnetic field without physical interference.
   • Avoid placing the sensor near strong electromagnetic fields that could affect its performance.

5. Handling:

   • Handle the sensor with care to avoid damaging the sensitive components.
   • Follow proper ESD (Electrostatic Discharge) precautions during handling and installation.

6. Testing:

   • To test the sensor, apply a magnetic field to the sensor and observe the output state change using a multimeter or an LED connected to the output.

7. Troubleshooting:

   • If the sensor does not respond, check the power supply connections and ensure the pull-up resistor is correctly installed.
   • Verify that the magnetic field strength is within the specified range.

By following these instructions, you can effectively integrate the GJ-SH-112DM Hall Effect Sensor into your project.
