Instructions for Use:
Power Supply:
- Connect the Vcc pin to a power supply within the range of 4.5V to 5.5V.
- Connect the GND pin to the ground of the power supply.
Output Connection:
- The output is an open collector, so connect a pull-up resistor between the output pin and Vcc.
- The output will be low (0V) when the sensor detects a magnetic field of at least 30G.
- The output will be high (Vcc) when no magnetic field is detected.
Mounting:
- Ensure the sensor is mounted in a location where it can detect the magnetic field without interference from other magnetic sources.
- The sensor is sensitive to both north and south poles due to its bipolar nature.
Temperature Considerations:
- Operate the sensor within the temperature range of -40°C to +85°C to ensure reliable performance.
Handling:
- Handle the sensor with care to avoid damage to the pins or the package.
- Avoid exposing the sensor to excessive mechanical stress or moisture.
Testing:
- To test the sensor, bring a magnet close to the sensor and observe the output change.
- The output should switch from high to low when the magnetic field strength exceeds 30G.
Storage:
- Store the sensor in a dry, cool place away from strong magnetic fields and static electricity.
