Instructions for Use:
Power Supply Connection: Connect the supply voltage between 2.5V and 5.5V to the VCC pin, ensuring a stable power source is used.
Ground Connection: Connect the GND pin to the system ground.
Output Signal: The output pin (OUT) will provide a digital signal that switches based on the presence of a magnetic field. Ensure this pin is connected to the input of your microcontroller or logic circuit.
Adjusting Sensitivity: Sensitivity can be adjusted using an external resistor connected to the sensitivity adjustment pin (SA). Refer to the datasheet for specific resistor values corresponding to desired sensitivity levels.
Mounting: Mount the sensor in a location where it can effectively detect the magnetic field changes intended for sensing.
Handling Precautions: Avoid exposing the device to temperatures outside its operating range (-40掳C to +85掳C).
Testing: Before final integration, test the sensor in a controlled environment to ensure it meets the required performance criteria.
