Hall Effect Sensor Module

Detect magnet proximity with compact size

• Spec name: Hall Effect Sensor Module
• Size: Compact
• Operating Voltage Range: 4.5 – 24 volts
• Threshold: 35-450 Gauss
• Hysteresis: 20 Gauss
• Sensor: Allegro MicroSystems A3144EUA
• Interface: 3-pin (Signal, V+, GND)

Key Features:

• Compact design
• Detects magnet proximity
• Open-collector output transistor
• Fast response time

When the magnetic field surpasses the threshold level, the open-collector output transistor is triggered, pulling the logic-compatible output low and lighting up the onboard LED indicator. To operate this sensor, add a 10K pull-up resistor between the “S” pin and the middle pin (+), connect the “-” pin to ground, and supply voltage to the middle pin. The “S” pin will go low (grounded) and the onboard LED indicator will activate upon detecting a magnet in close proximity.
