The MLX90614 is a high-precision, non-contact infrared (IR) thermometer that measures temperature from a distance by detecting emitted infrared radiation. In simulation environments like Proteus 8 Professional, this sensor is not included in the default component database. To use it, you must manually install a third-party library to provide the schematic model and simulation behavior. 1. Key Features of the MLX90614 Measurement Range: Ambient temperature from and object temperature from High Precision: Includes a 17-bit ADC with a resolution of
Communication Interface: Uses the I2C-compatible SMBus protocol for easy connection to microcontrollers like Arduino.
Contactless Sensing: Ideal for measuring moving machinery, hazardous materials, or medical use cases where physical contact is impossible. 2. How to Install the MLX90614 Proteus Library
Since Proteus does not natively support the MLX90614, you must download a library (often found on platforms like The Engineering Projects) and follow these steps: mlx90614 proteus library
MLX90614 Infrared Thermometer Sensor Library for Proteus
The MLX90614 is a non-contact infrared thermometer sensor that can measure the temperature of an object without physically touching it. It is widely used in various applications such as temperature monitoring, heat detection, and thermal imaging. In this article, we will discuss how to use the MLX90614 library in Proteus, a popular circuit simulation software.
Introduction to MLX90614
The MLX90614 is a miniature infrared thermometer sensor that uses a thermopile detector to measure the infrared radiation emitted by an object. It has a high accuracy of ±0.5°C and a wide temperature range of -20°C to 120°C. The sensor communicates with the microcontroller using I2C protocol.
Proteus Library for MLX90614
To simulate the MLX90614 sensor in Proteus, we need to add the library to the software. Here are the steps to follow: The simulated component typically mirrors the physical TO-39
Using the MLX90614 Library in Proteus
Once you have added the library to Proteus, you can start using it in your project. Here are the steps to follow:
Simulation and Testing
Once you have set up the MLX90614 component in your Proteus project, you can simulate and test its functionality. Here are the steps to follow:
Example Code
To demonstrate the use of the MLX90614 library in Proteus, here is an example code in C: Do you have a verified MLX90614 library file
#include <16F877A.h>
#include <MLX90614.h>
void main()
// Initialize the MLX90614 component
MLX90614_Init();
while (1)
// Read the temperature
float temperature = MLX90614_ReadTemperature();
// Display the temperature on the virtual terminal
printf("Temperature: %.2f°C\r\n", temperature);
// Delay for 1 second
delay_ms(1000);
This code initializes the MLX90614 component, reads the temperature, and displays it on the virtual terminal.
Conclusion
In this article, we discussed how to use the MLX90614 library in Proteus to simulate and test the functionality of the infrared thermometer sensor. We covered the steps to download and add the library to Proteus, configure the component, and simulate and test its functionality. We also provided an example code to demonstrate the use of the MLX90614 library. With this library, you can design and test your projects that use the MLX90614 sensor in a simulated environment before moving to the hardware implementation.
To simulate the MLX90614, a specific library model must be imported into the Proteus environment. This process involves two distinct components: the schematic symbol and the simulation model.
Approach: create a Proteus VSM (Virtual System Modelling) device using either:
