Close Proteus if it is open. Open it again to refresh the component list. Building the Circuit in Proteus
If you are using an Arduino or ESP8266 in your simulation, you also need a software library to handle the I2C (SMBus) communication. MLX90614 - Arduino Library List
: This indicates an I2C communication failure. Check your SDA/SCL wiring and verify that you included the 4.7kΩ pull-up resistors on both communication lines.
This report details the integration of the into Proteus for circuit simulation. Since the MLX90614 is not a built-in component in standard Proteus libraries, it requires custom library files and an I2C-compatible microcontroller (like Arduino) for operation. 1. Component Overview: MLX90614 mlx90614 proteus library
: Open the "Pick Devices" window (press 'P') and search for "MLX90614" or "Infrared Sensor". Load HEX File
void setup() Serial.begin(9600); mlx.begin();
: An index file that allows Proteus to search for the component in the "Pick Devices" window.
Complete Guide to Using the MLX90614 Proteus Library for Infrared Temperature Simulations // Instead of actual I2C read float getTemperature()
To simulate the MLX90614, follow these steps to install the necessary library files:
To drive the simulation, you need to compile code that talks to the sensor over I2C. You will need the standard Adafruit_MLX90614.h library installed in your Arduino IDE.
Click the small up and down arrows on the virtual MLX90614 sensor. This changes the simulated heat. Watch the LCD screen update instantly. Troubleshooting Tips
