Reliable data output

Using this for a university project. The FIFO buffer helps prevent data loss during high-speed sampling. Highly recommended for students and makers.

Excellent documentation support

I had a question about the register map, and the support team provided a helpful link immediately. The sensor detects pulse waves clearly on the oscilloscope.

Compact and efficient

Small form factor makes it easy to integrate into wristband designs. Power consumption is low. Just ensure you use a proper level shifter if running at 5V logic.

Good sensor, needs calibration

The hardware quality is solid. Readings are consistent once you calibrate the LED intensity settings in the code. Shipping was very fast as promised.

Perfect for wearable prototypes

This module works flawlessly with my ESP32 project. The I2C communication is stable, and the library support is excellent. Great value for electronic development.

5 FAQ

Q: Is this module compatible with 5V Arduino Uno boards?

A: Yes, but since the MAX30102 operates at 1.8V/3.3V, we recommend using a logic level converter or an I2C breakout board with voltage regulation to ensure safe communication.

Q: Does this come with example code for Raspberry Pi?

A: While we do not include physical code sheets, our website hosts a GitHub repository with Python examples specifically for Raspberry Pi and C++ libraries for Arduino.

Q: How quickly do you ship after ordering?

A: As stated in our description, orders placed before 2 PM local time are shipped the same day. You will receive a tracking number via email immediately upon dispatch.

Q: Can I daisy-chain multiple modules on the same I2C bus?

A: The standard module has a fixed I2C address. To use multiple sensors, you would need to modify the hardware to change the address pins or use an I2C multiplexer.

Q: What is the maximum distance the sensor can read through?

A: This is a reflective sensor designed for direct skin contact or very close proximity (within a few millimeters). It is not designed for long-distance detection.
