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 onboard LED indicator.

The Hall Effect Magnetic and Proximity Sensor Module can be used to detect the presence (or absence!) of nearby objects such as magnets. This sensor accepts a GND and +5V supply and has a single digital output which goes low (GND) when a magnetic field is detected.

The linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. It has a reduced current consumption of only 6 mA typically at 5 Vdc helps make this sensor energy efficient.
