Hall Effect 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.

Module with Hall sensor with analog and digital output. It works with voltage from 2.3 V to 5.3 V. It provides the detection of a magnetic field. The output voltage of the sensor is proportional to the value of the induction of the magnetic field.

Connections: 

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

features: 

1. 49E hall sensor
2. Features wide-range voltage comparator LM393
