HALL EFFECT SENSOR(LINEAR MAGNETIC HALL SENSOR)

The Linear Magnetic Hall Sensor module detects magnetic fields and outputs both an analog voltage (proportional to field strength) and a digital signal (via LM393 comparator). Adjustable sensitivity via onboard potentiometer. Onboard LED indicator lights when a magnetic field is detected. 4-pin interface (VCC, GND, AOUT, DOUT) compatible with 3.3V and 5V microcontrollers.

Pin Configuration:

• VCC — 2.3–5.3V
• GND — Ground
• A_OUT — Analog output (to MCU ADC)
• D_OUT — Digital output (to MCU digital IO)

Specifications:

• Comparator: LM393
• Operating Voltage: 3.3–5V
• Dimensions: 35 × 15 × 14mm
• Weight: 3g
• Adjustable sensitivity via potentiometer

Applications:

• Motor speed measurement
• Object and position detection
• Smart car encoder systems
• Magnetic field proximity sensing
