The Hall Magnetic Sensor Module is a switch that will turn on/off in the presence of a magnetic field. If no magnetic field is present, the signal line of the sensor is HIGH (3.5 V). If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time the LED on the sensor lights up. An onboard LED will also indicate the presence of a magnetic field.

Precision and high reliability 3144 Series Hall principle of Hall effect switch IC, using technology to produce magnetic semiconductor integrated circuit, which is determined by the voltage regulator, Hall voltage generator, differential amplifier, Schmidt trigger, temperature compensation circuit and the collector electrode open circuit output stage consisting of magnetic sensing circuit, the input for the magnetic flux density, the output is a digital voltage signal.

This module is an analog magnetic field sensor. The strength of the field is given by an analog voltage at the signal pin of the module. The sensor must be connected to GND and 5V of the Arduino board. The output voltage is measured by analog pin A5 on the Arduino board.

The example program measures the output voltage of the sensor and presents the measured value in the serial monitor of the Arduino. The LED on the board flashes at a speed dependent on the strength of the magnetic field. This can be demonstrated with a small magnet.

This module has application in Non-contact switch Car ignition Brake circuit Position, speed detection and control Security alarm device Textile control system.
