Magnetic Hall Effect Sensor(KY-024) Library for Proteus

What is Magnetic Hall Effect Sensor?

• Magnetic Hall Effect Sensor is used to measure the density of magnetic field in the surroundings using Hall Effect Principle.
• KY-024 is the sensor's model used for measuring magnetic density.
• There are many different breakout boards available but they all are using the same sensor i.e. KY-024.

Magnetic Hall Effect Sensor Library(Ky-024) for Proteus

• First of all, download the Proteus Library zip file for Magnetic Hall Effect Sensor, by clicking the below button:

• In this zip file, we need to open the folder titled Proteus Library Files.
• In this folder, you will find three Proteus Library files, named:
  • MagneticHallEffectSensorTEP.IDX
  • MagneticHallEffectSensorTEP.LIB
  • MagneticHallEffectSensorTEP.HEX
• We need to place these files in the Library folder of our Proteus software.

• If you are facing problems with adding a library in Proteus 7 or 8 Professional, then have a look at How to add a new Library in Proteus 8 Professional.

• Now, open Proteus ISIS and if you are already working on it, restart it.
• In the components search box, make a search for "Magnetic Hall" and you will get four results, as shown in the below figure:

• Let's place these four Hall Effect sensors' models in our Proteus workspace.

KY-024 Proteus Simulation

• As we have seen this simulated model of KY-024 has five pins in total:
  1. A0: Analog output.
  2. G: Ground.
  3. V: Vcc (Power).
  4. D0: Digital output.
  5. Test: For testing purposes.

Why Test Pin is used?

• As it's stimulation, so we can't actually create a magnetic field around the sensor, that's why we have placed this Test Pin.
• As the voltage at Test Pin will increase, the sensor will consider it as magnetic density is increasing around.
  • If Test Pin is at 0V, the sensor will feel no magnetic field.
  • If Test Pin is 5V, the sensor will feel a maximum magnetic field.
• We will attach a potentiometer to the Test Pin, for variable voltage levels.

Adding Hex File to the sensor

• In order to operate the magnetic Hall Effect sensor, we need to add a hex file in its properties panel.(We have placed the hex file in the Library folder)
• So, double click on your sensor to open its properties panel.
• In the Upload Hex File section, browse to your sensor's hex file, as shown in below figure:

• After adding the hex file to the sensor, click on the Ok button to close the properties panel.

Proteus Simulation of Magnetic Hall Effect Sensor

• Now, let's design a simulation in Proteus software, as shown in the below figure:

• I have attached an LED with the digital output of the sensor and a voltmeter with analog output.
• I have also placed a simple LC filter at the analog output. This filter is not required in real hardware implementation.
• We are using it in Proteus simulation, as Proteus gives the peak to peak value and we have to convert that PP value into Vrms.
• If you are working on a real sensor then you don’t need to add this LC circuit.
• Now, let's run our simulation and if everything's configured correctly, you will get results as shown in the below figure:

• As you can see in the above figure, our sensors are working perfectly, now if you change the value of the potentiometer, their output will change accordingly.
