Download and Install the ACS712 Current Sensor Library for Proteus Software for Simulation
In the world of electrical engineering, accurate current measurement is a fundamental requirement for various applications. Whether you’re designing power monitoring systems, energy meters, or battery management solutions, having the right simulation tools is crucial. Proteus, a widely used simulation software, allows engineers to design and test electronic circuits virtually. However, by default, it does not include all the components needed for advanced simulations, such as the ACS712 current sensor module.

The ACS712 current sensor is a highly precise and widely used module that helps measure AC and DC currents efficiently. To integrate it into Proteus for simulation, you need to download and install the ACS712 current sensor library manually. In this guide, we will walk you through the step-by-step process of adding the ACS712 sensor module to Proteus. By following these instructions, you will be able to simulate current measurements effectively in your circuit designs.
What is the ACS712 Current Sensor?
The ACS712 is a Hall-effect-based linear current sensor manufactured by Allegro Microsystems. It provides accurate current sensing with minimal power loss, making it an excellent choice for various applications. The module is available in different versions, each supporting different current ranges:
- ACS712-05A: Measures up to 5A
- ACS712-20A: Measures up to 20A
- ACS712-30A: Measures up to 30A
These sensors output an analog voltage proportional to the detected current, which can be interfaced with microcontrollers like Arduino, ESP32, and PIC microcontrollers for real-time monitoring.

Step 1: Download the Library Files
First, you need to download the ACS712 current sensor library for Proteus. You can find the library download link in the button below.
Step 2: Extract the Downloaded File
After downloading the library, extract the ZIP file. Inside the extracted folder, you will find two important subfolders:
- Library Folder (Contains essential library files)
- Models Folder (Contains different ACS712 sensor models: 5A, 20A, and 30A)
Step 3: Copy Library Files to Proteus
- Open the Library folder from the extracted files.
- Copy the
.IDX
and.LIB
files found inside. - Locate your Proteus installation directory on your computer. Typically, it is found at:
C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY
- Paste the copied files into the LIBRARY folder.
Step 4: Copy Models Files to Proteus
- Open the Models folder from the extracted files.
- Copy all the
.MDL
files found inside (5A, 20A, and 30A models). - Locate the Models directory in your Proteus installation:
C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\MODELS
- Paste the copied files into the MODELS folder.
Step 5: Restart Proteus
To ensure the newly added components are recognized, close Proteus if it is already open. Restart the software so that it can update the library database.
How to Use the ACS712 Sensor in Proteus
