Paste them directly into the Proteus LIBRARY folder located in Step 2.
However, for professional PCBs with multiple peripherals, Proteus remains superior, and the custom MLX90614 library is still the best workaround.

By default, the standard Proteus component library does not contain a pre-built simulation model for the MLX90614. Attempting to draw a schematic without a specific simulation model presents several challenges:
Verify that the correct hex file is loaded into the Arduino model. mlx90614 proteus library
Before starting the simulation, it is essential to understand how the sensor communicates.
float readTemperature() int16_t rawTemp;
To simulate the MLX90614 sensor in Proteus, we need to add the library to the software. Here are the steps to follow:
: Close and reopen Proteus for the new component to appear in the "Pick Devices" (P) menu. 2. Sensor Pinout & Interfacing Paste them directly into the Proteus LIBRARY folder
The sensor measures both ambient temperature (the air around it) and object temperature (the target surface).
A real MLX90614 arrived from DigiKey. He wired it to an Arduino Nano, not Proteus. He wrote a quick sketch. The sensor saw his finger from 10cm: 34.2°C. His coffee: 68.5°C. The window: 12.1°C. Real. Perfect. Alive.
The MLX90614 communicates via SMBus. While similar to I2C, SMBus has specific timing and protocol requirements. The standard I2C library in Arduino ( Wire.h ) can be adapted, but using a specific MLX90614 library (such as the Adafruit MLX90614 library) simplifies implementation significantly.
