Instructions for Use
Power Supply:
- Connect the VCC pin to the positive terminal of your power supply.
- Connect the GND pin to the ground terminal of your power supply.
Output Connection:
- The OUT pin is an open collector output. Connect it to the input of your microcontroller or other device.
- A pull-up resistor (typically 4.7kΩ to 10kΩ) should be connected between the OUT pin and VCC to ensure a high state when no magnetic field is detected.
Magnetic Field Detection:
- Place a magnet near the sensor. The sensor will detect the magnetic field and the output will go low (0V).
- When the magnet is removed, the output will return to high (VCC level).
Mounting:
- Ensure the sensor is securely mounted in the desired location.
- For surface mount applications, solder the sensor directly to the PCB.
- For through-hole applications, insert the pins into the PCB and solder them in place.
Testing:
- Apply power to the sensor.
- Bring a magnet close to the sensor and observe the output state change.
- Use a multimeter to verify the output voltage levels.
Handling:
- Handle the sensor with care to avoid damage.
- Avoid exposing the sensor to extreme temperatures or humidity.
Troubleshooting:
- If the sensor does not respond, check the power connections and ensure the pull-up resistor is correctly installed.
- Verify that the magnet is strong enough and positioned correctly relative to the sensor.
