Linear Magnetic Hall Sensor

Input and Output

• Input: Magnetic field (both direction and strength).
• Output: Analog voltage signal that varies with the magnetic field strength.

Physical Characteristics

• Material: Usually housed in a plastic or epoxy-coated package.
• Dimensions: Small and compact, typically a few millimeters in length and width.
• Weight: Very lightweight.

Technical Specifications

• Sensitivity: Typically around 1.3 mV/Gauss.
• Output Linearity: Linear relationship between magnetic field strength and output voltage.
• Operating Range: -40°C to +85°C, suitable for various environments.

Additional Features

• Bidirectional Sensitivity: Detects both north and south poles, with output voltage increasing for one pole and decreasing for the other.
• Easy Integration: Simple to connect to microcontrollers for analog signal processing.

How to Use

• Connect the Sensor: Connect the Vcc pin to a 3.3V or 5V power supply, the GND pin to the ground, and the Out pin to an analog input on your microcontroller.
• Position the Magnet: Place a magnet near the sensor to measure the magnetic field. The output voltage will change proportionally to the magnetic field’s strength and polarity.
• Read the Output: Use an analog-to-digital converter (ADC) in your microcontroller to read the output voltage and interpret the magnetic field strength.
• Calibrate if Necessary: Adjust the sensor’s position or the code in your microcontroller for precise readings based on your application.

The Linear Magnetic Hall Sensor is ideal for applications requiring accurate detection and measurement of magnetic fields, such as in position sensing, current measurement, and proximity detection.
