MLX90614 Proteus Library — Short Paper

Abstract

This document describes creating and using a Proteus-compatible library for the MLX90614 infrared (IR) temperature sensor (I2C, SMBus). It covers component model design, symbol and PCB footprint, electrical behavior, I2C communication, limitations, verification, and example simulation setup.

4. Practical Alternative – Skip Simulation

Simulate the I2C communication logic using a generic I2C slave in Proteus.
Test actual MLX90614 hardware with a physical board (Arduino, ESP32).
Use software simulation (Wokwi, SimulIDE, or PlatformIO) that supports MLX90614.

2.2 Installation Procedure

File Placement: Navigate to the Proteus installation directory, typically C:\Program Files (x86)\Labcenter Electronics\Proteus X Professional\LIBRARY. Copy the downloaded library files (.LIB and .IDX) into this folder.
Library Indexing: Open Proteus ISIS. Open the "Library" menu and select "Library Manager." Click "Indexing" -> "Update Index" to ensure Proteus recognizes the new files.
Component Retrieval: Click the "P" button (Pick from Libraries) and search for "MLX90614."

Once upon a time, a young engineer named was tasked with building a high-tech medical kiosk that could measure a person's temperature without touching them. He chose the Melexis MLX90614 MLX90614 Proteus Library — Short Paper Abstract This

Double-click the component to view:

Ambient Temperature (TA): Default 25°C. The library will return this when reading RAM address 0x06.
Object Temperature (TOBJ1): Default 25°C. Returns at address 0x07.
I2C Slave Address: Usually 0x5A (binary 1011010). Real sensors can be changed to 0x5B by bridging the ADDR pin to VDD.
Emissivity Setting: Usually fixed at 0xFFFF (1.00) in basic libraries, but advanced models allow adjustment (Range: 0.1 to 1.0).

, a powerful infrared sensor known for its non-contact precision. However, before building the physical prototype, Leo needed to prove his circuit worked in Proteus Design Suite. Simulate the I2C communication logic using a generic
