Description:
The Hall Effect Sensor Module is designed to detect the proximity of a magnet and is compact in size. When the magnetic field exceeds a specified threshold, the open-collector output transistor activates, pulling the logic-compatible output low and illuminating the onboard LED indicator.
This sensor is fast and operates within a turn-on threshold of 35–450 Gauss, with a minimum hysteresis of 20 Gauss. It functions within a voltage range of 4.5 to 24 volts and uses the Allegro Microsystems A3144EUA sensor. The module features a 3-pin interface: signal, V+, and GND.
To use the sensor, connect a 10K pull-up resistor between the “S” pin and the V+ pin, and attach the GND pin to ground. When a magnet is brought close, the “S” pin will go low (pulled to ground), turning on the onboard LED indicator.
The sensor detects the magnetic field and outputs an analog voltage value. You can adjust the sensitivity of the sensor using a potentiometer.
Pin Configuration:
- VCC → 2.3V ~ 5.3V
- GND → Power supply ground
- AOUT → MCU.IO (Analog output)
- DOUT → MCU.IO (Digital output)
Applications:
- Motor speed measurement
- Object position detection
- Smart car
- Electronic bricks
Features:
- Features wide-range voltage comparator LM393
- Adjustable sensitivity
- Signal output indicator with retaining bolt hole for easy installation
- Output form: Digital switch output (0 and 1 high and low level)
- Signal output indication
- Single-channel signal output
- Output effective signal is low level
- When magnet is detected, outputs low level and LED indicator turns ON
- Can be used for sound-controlled light systems, alarms, and paired with other sensors
