How to make MAGNETIC FIELD Finder using Hall Effect Sensor with Arduino

Key Characteristics:

Voltage Output: Linear Hall Effect sensors provide an analog voltage output that changes linearly with the strength of the magnetic field. The voltage range typically depends on the sensor model and the supply voltage used.

Sensitivity: Sensitivity refers to the change in output voltage per unit change in magnetic field strength. It's usually specified in millivolts per Gauss (mV/G) or millivolts per Tesla (mV/T). Different sensors have different sensitivities to suit different applications.

Supply Voltage: Linear Hall Effect sensors operate within a specific supply voltage range. Common supply voltages are 3.3V and 5V.

Zero Gauss Voltage (Vz): This is the output voltage when no magnetic field is applied. It's the point around which the output voltage changes linearly with respect to the magnetic field.

Operating Temperature Range: Linear Hall Effect sensors have specified temperature ranges in which they operate accurately.

Applications:

Linear Position Sensing: These sensors are commonly used to measure linear displacement or position, often in industrial and automotive applications.
Current Sensing: They can be used to measure current by placing a conductor carrying the current close to the sensor.
Rotational Sensing: In combination with a magnet, they can measure rotational angles or positions.
Proximity Detection: They can be used to detect the presence of a magnetic object.
Wiring and Usage:
To use a Linear Hall Effect sensor, you would typically connect its power supply pins (VCC and GND) to appropriate voltage sources and ground. The output pin (OUT or DO) would be connected to an analog or digital pin on a microcontroller, like an Arduino, to read the analog voltage or digital state.

Keep in mind that the specific connections and usage details might vary depending on the sensor's datasheet and your application requirements.

Before using the sensor, always refer to the manufacturer's datasheet to understand its specifications, proper operating conditions, and how to interpret its output voltage with respect to the magnetic field.
