If you have Proteus open, close the software completely and relaunch it. This forces the application to re-index its database and incorporate the newly added MLX90614 sensor model. Setting Up the Schematic Circuit in Proteus
Once the library is installed, you can build your simulation circuit. Finding the Component Open the window in Proteus.
Using a custom MLX90614 library inside Proteus saves engineering hours by pointing out logic flaws and firmware communication bus errors early, ensuring a smoother transition to your physical PCB layout.
Navigate to the directory where Proteus stores its library models. The file path varies depending on your software version: mlx90614 proteus library
void loop() float ambient = readTemp(0x06); float object = readTemp(0x07); Serial.print("Ambient: "); Serial.print(ambient); Serial.print("
Since Proteus does not natively support the MLX90614, you must download a library (often found on platforms like The Engineering Projects ) and follow these steps:
Once you have set up the MLX90614 component in your Proteus project, you can simulate and test its functionality. Here are the steps to follow: If you have Proteus open, close the software
: Download the MLX90614 library package from a reliable source like The Engineering Projects Identify Library Files : Ensure you have three essential files: InfraredSensorsTEP.LIB InfraredSensorsTEP.IDX InfraredSensorsTEP.HEX
: Close and reopen the software to refresh the component database.
The MLX90614 operates entirely over I2C. Connect the pins as follows: MLX90614 Pin Arduino Uno Pin Description Power Supply GND SDA Serial Data Line (Requires 4.7kΩ pull-up to VCC) SCL Serial Clock Line (Requires 4.7kΩ pull-up to VCC) Finding the Component Open the window in Proteus
This comprehensive guide covers everything you need to download, install, and simulate the MLX90614 sensor within Proteus VSM. Understanding the MLX90614 Sensor
