#include <stdbool.h>
#include <avr/io.h>
#include <avr/interrupt.h>
#define MLX90614_I2C_ADDRESS 0x5A
void mlx90614_init() 
  // Initialize I2C communication
  TWBR = 0x18; // 100 kHz
  TWSR = 0x00;
uint16_t mlx90614_read_temperature()  (1 << TWSTA);
  while (!(TWISr & (1 << TWINT)));
  TWIDR = (MLX90614_I2C_ADDRESS << 1)
int main() 
  mlx90614_init();

Conclusion

The MLX90614 library for Proteus provides a convenient way to simulate and test the MLX90614 infrared thermometer in your electronic circuits. By following the steps outlined in this write-up, you can easily add the MLX90614 to your Proteus schematic and start simulating and testing your projects.

The MLX90614 Proteus library is a custom simulation model designed to bridge the gap between physical hardware and virtual circuit design for the Melexis MLX90614 non-contact infrared temperature sensor. Because Proteus does not include a native model for this specific I2C-based sensor, users typically rely on third-party libraries—most notably those from The Engineering Projects. Key Features of the Proteus Library

Virtual Interaction: Since physical IR waves cannot be simulated in Proteus, these libraries often use a TestPin to mimic the presence of an object. Applying a HIGH or LOW voltage to this pin triggers the sensor's response in the simulation.

Protocol Support: The library accurately models the SMBus/I2C communication, allowing it to interface with microcontrollers like the Arduino Uno or Nano within the Proteus workspace.

Visual Representation: It provides a specific LIB (library) and IDX (index) file that adds the TO-39 package component to your Proteus "Pick Device" list. Review of Strengths & Limitations New Proteus Libraries of Digital Sensors

The MLX90614 Proteus library is a third-party simulation model designed to test non-contact temperature sensors by enabling I2C communication and simulating both object and ambient temperature ranges. It features an interactive, high-resolution modeling setup (17-bit ADC) essential for virtual testing with microcontrollers such as Arduino, though it requires manual installation into the Proteus library folder.
