Copy the MAX30100.LIB and MAX30100.IDX files you downloaded.
Ensure you have added I²C pull-up resistors to the SDA and SCL lines (usually 4.7k Ωcap omega Ωcap omega ) in your Proteus schematic. B. Library Not Appearing (Library Error) If the component still does not show up:
The MAX30100 is a low-power, high-performance pulse oximeter and heart rate sensor from Maxim Integrated. It measures oxygen saturation (SpO2) and heart rate (HR) using a technique called photoplethysmography (PPG). The sensor is widely used in fitness trackers, smartwatches, and other wearable devices.

The MAX30100 runs at . If you connect it to a 5V Arduino (simulated as 5V on SDA/SCL), the model will crash. Use a virtual voltage regulator (3.3V) for the sensor's VDD and ensure the I2C lines are pulled to 3.3V, not 5V.
Users may face several issues when trying to download and integrate the MAX30100 library into Proteus, including:
Nothing.
Add a connected to the Arduino TX/RX pins to display the calculated BPM (Beats Per Minute) and SpO2 (Oxygen Saturation) percentages.
You have designed a brilliant wearable health monitor. You have written the Arduino code for the MAX30100 sensor to measure heart rate and SpO2. You are ready to simulate the entire circuit in Proteus to save time and hardware costs. But then comes the roadblock:
Most people give up and buy real hardware. But you? You’ve tamed the ghost. Now go build that pulse oximeter simulation – and never trust a random .IDX file again. Copy the MAX30100
The most effective workaround is using the library, which you can find in a community-curated repository. This library has been tested by developers and is specifically intended to model the behavior of an oximeter sensor, making it a near-perfect substitute for the MAX30100 in your simulations.
Proteus does not automatically detect files in the "Downloads" folder. You must manually move them:
The installation path varies depending on your Windows version and Proteus release: Library Not Appearing (Library Error) If the component
