The hall effect sensor we will use in this circuit is an A1302 hall effect sensor manufactured by Allegro.
Each sensor output (H+ and H-) is connected to a comparator (LM339) which therefore gives a single output as shown in the circuit diagram above. Based on the relation between hall voltage and magnetic flux density, Hall Effect sensors are of two types. Today, Hall effect devices are included in many products, ranging from computers to sewing machines, automobiles to aircraft, and machine tools to medical equipment. As you can see, the hall effect sensor arduino circuit diagram is pretty simple. The hall sensor works on the principle of Hall Effect, which states the whenever a magnetic field is applied in perpendicular direction to the flow of the current, then a potential difference is induced. The hall effect sensor explained above can be quickly configured through a few external parts for converting magnetic field into electrical toggling pulses for controlling a load. With this circuit, we will be able to detect when any mangets in proximity of our circuit.
However, I see in LTspice some issues with low current consumption. Direct sensing has 2 methods: High-side and low-side sensing. While using a gain of 10 will mean 1v per 1A which is a lot easy and practical. Battery Powered Lamp That Turns on Through the Use of Magnets. In the threshold sensor, at each magnetic flux density, the output voltage will have a sharp decrease. Hall Effect current sensor circuit. The used motor has 3 hall effect sensors as any sensored brushless motor, each hall effect sensor has 4 pins: VCC, GND, H+ and H-. A hall effect sensor is a sensor which detects magnetic fields. This will give the voltage difference directly as it is. Hall Effect sensors can be viewed as linear transducers. Hi! In the threshold sensor, at each magnetic flux density, the output voltage will have a sharp decrease. This op-amp configuration is called “differential amplifier” which it amplifies the voltage difference between its inputs. Since I have 4-pin hall effect sensors, I added an analog comparator (I used LM339N quad comparator IC) to each one so each sensor outputs (2 outputs: + and -) are connected to the inputs (2 inputs: non-inverting and inverting) of the comparator as shown in the circuit schematic below, finally I got 3 outputs from the 3 hall effect sensors. I also attached the slides for those who want them!
The working of this circuit is very simple. Monitoring the Current flow in a device by a mains powered appliance is just complicated one. using the Hall effect. Because continuous current flow monitoring by a circuit creates current isolation in target device, so we need to measure current flow without affecting the target device. Do you have any advice on how to deal with that?
These methods are suitable more for high current systems. Question These methods are suitable more for high current systems.
Hall effect sensor Circuit.
For the first time, a Hall effect sensing element and its associated electronics were combined in a sin-gle integrated circuit. The op-amp will amplify the voltage difference between its two inputs according to this equation (also in the figure): If all 4 resistors where the same value(like 10k) this will be a unity gain differential amplifier which the output voltage is: [ V_out = V2 – V1 ] since R3/R1 = 1/1 = 1. 3- put the probes as the figure to close the circuit. ALL that is here and more you can watch it on my channel VEGEtek on youtube (episode 003). Hall Sensor reacts to magnetic field and changes its output depends on the polarity of magnet and magnetic field strength still now used in many applications, by using this types of sensor we can create multipurpose hall effect sensor circuit. Ways to measure current: 1- Indirect method: such as current transformers (in the figure) and Hall effect sensors, which relies on Faraday's law of induction to sense current in a circuit and convert it to a proportional voltage. It seems to work quite well.

When the R6 resistor in your LTspice schematics is around 200 ohms for instance (or more, leading to current consumption of around 60mA and lower), the LT1678 output starts to lose accuracy and then saturates around 56mv. The circuit diagram for controlling a 5V Relay Module with Hall Effect Sensor and Arduino is shown below. Working.
In the linear sensor, the output voltage is linearly related to magnetic flux density. Place the readings facing you and the first pin on your left is the Vcc and then Ground and Signal respectively. 2- Direct method: which relies on Ohm’s law which states that V = I x R. This method is suitable for low currents and widely used in electronics devices. Whenever the Hall Effect Sensor is subjected to a magnetic field, it toggles the Relay (as per the code). Control a Relay with Arduino and Hall Effect Sensor. Thanks for the great tutorial. 1- Indirect method: such as current transformers (in the figure) and Hall effect sensors, which relies on Faraday's law of induction to sense current in a circuit and convert it to a proportional voltage. In the linear sensor, the output voltage is linearly related to magnetic flux density. However, it is common to have a gain of 10 or so in such practical circuits because the voltage difference may be so small, for example: If shunt resistor is 0.1 Ohms (very common) and the current is 1A, this will result in 1 x 0.1 = 0.1v across shunt resistor, this will mean 0.1v output of the differential amplifier when unity gain is used, so it is 0.1v per 1 A.
