Linear Magnetic Hall Sensor Module

Linear Magnetic Hall Sensor Module is used to Detect the proximity of a magnet. It is very much Smaller in size. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the on board LED indicator.

To use this linear hall sensor/switch, place a 10K pull-up resistor between the “S” pin and the middle pin (+), connect the “-” pin to ground. Supply voltage to the middle pin. The “S” pin will go low (gets pulled to ground) and the on board LED indicator will turn on when a magnet is brought near. It has a 4 pin interface with analog signal, digital signal, V+ and GND.

• VCC ↔ 2.3V ~ 5.3V
• GND ↔ power supply ground
• AOUT ↔ MCU.IO (analog output)
• DOUT ↔ MCU.IO (digital output)

• Motor speed measurement
• Object position detection
• Smart car
• Electronic bricks

• 1 x Linear Magnetic Hall Effect sensor
