The MLX90614 is a contactless IR temperature sensor with a digital SMBus/I2C output (addressable), commonly used to measure object and ambient temperatures. Proteus lacks an official behavioral model for the device; creating a custom library enables circuit simulation and firmware testing.
You cannot cleanly place the sensor on your schematic diagram. mlx90614 proteus library
Connect the SDA pin of the MLX90614 to the corresponding SDA pin on your microcontroller (Pin A4 on Arduino Uno). Connect the SCL pin to the SCL pin on the microcontroller (Pin A5 on Arduino Uno).
If you are looking to purchase the sensor, you can find it on DFRobot or SparkFun. If you'd like, let me know: Which are you using (Arduino, PIC, ESP32)? Connect the SDA pin of the MLX90614 to
Once the simulation begins running, look closely at the MLX90614 component model in your schematic. Most high-quality Proteus libraries embed small or "Up and Down" toggle arrows right on the body of the graphic component.
If you want, I can generate:
