Instructions:
- Installation: Ensure the sensor is mounted in a location where it can reliably detect the magnetic field without physical interference.
- Power Supply: Connect the VCC pin to a power supply between 3.3V and 5.5V DC, and GND to the ground.
- Signal Output: The OUT pin provides an open collector output which can be connected to a pull-up resistor or directly to a microcontroller input pin.
- Magnetic Field Detection: Place a magnet close to the sensor to trigger the switch. Ensure the magnetic field strength is within the specified sensitivity range for reliable operation.
- Environmental Considerations: Avoid exposing the sensor to environments outside its operating temperature and humidity ranges to prevent damage or malfunction.
- Handling Care: Handle with care to avoid damaging the reed switch inside the sensor.
