First, it is helpful to briefly understand the sensor itself. The MAX30100 is an integrated pulse oximetry and heart-rate monitor module from Maxim Integrated (now part of Analog Devices). It incorporates two LEDs (one emitting red light, the other infrared), a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry (SpO₂) and heart-rate signals. Communication with a host microcontroller like an Arduino or ESP32 is achieved over a standard I²C bus.
Which (like Arduino Uno) are you connecting to the sensor?
Verify OXULLO Arduino MAX30100 Library is used in Arduino IDE.
#include <Wire.h>
Alternatively, if you are looking for alternatives, I can tell you about: The sensor (better performance). Using a Virtual Terminal in Proteus to debug I²C data. The best Arduino code for testing the simulation. max30100 proteus library download fix
Once you have the correct files, the installation process is the same for most third-party libraries.
To verify that your newly fixed library works, build this minimal test bench in Proteus:
If you need to test code behavior, replace the sensor model with an tool (found in the Virtual Instruments menu) to manually feed I2C hex data strings into your microcontroller. Fix 2: I2C Pull-Up Resistor Issue
I can provide a tailored solution or walk you through inside your schematic. Share public link First, it is helpful to briefly understand the sensor itself
You can create a that mimics MAX30100 behavior (returns heart rate/SpO₂ values). This requires C++ and Proteus SDK.
Run as Administrator, ensure proper Arduino Lib connections.
If a .HEX file is included, keep it in your project folder or the library folder to avoid "Fatal Simulation Errors".
Last updated: May 2026. Compatible with Proteus 8.9 SP3 to 8.17. Communication with a host microcontroller like an Arduino
Remember to add 4.7k ohm pull-up resistors to the SDA and SCL lines in your simulation, as many library versions require them to trigger the simulation logic correctly. Technical Specs: Operating Voltage: 1.8V - 3.3V Interface: I2C (Address: 0x57)
The Arduino IDE target .HEX file is uploaded into the virtual microcontroller chip.
Unlike physical breakouts, simulation environments sometimes struggle with default I2C behavior. to the SDA and SCL lines. 4. Code Compatibility (I2C Address)
