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.
