Works but sensitive to light
The sensor picks up ambient light interference easily. You need to shield it properly or use it in a dark enclosure for consistent SpO2 readings.

Excellent documentation support
Found plenty of example codes online for Arduino. The breakout board pins are clearly labeled, making wiring very easy for beginners.

Great learning tool
Bought this to learn about biometric sensors. It's small, low power, and the data output is easy to parse. Highly recommended for students.

Reliable for development
We use these in our workshop for various student projects. They are durable and handle repeated connections well. Just remember it's a development board, not a medical device.

Good sensor, needs calibration
The hardware quality is solid. However, getting accurate heart rate readings requires some software tuning and proper finger placement. Once calibrated, it works well.
Q: Does this come with a library for Python?
A: While we do not bundle a physical library, there are several open-source Python libraries available for Raspberry Pi and CircuitPython that support the MAX30102.
Q: What is the maximum distance for detection?
A: This is a contact-based sensor. The finger or skin must be in direct contact with the sensor surface for accurate readings; it does not work at a distance.
Q: Can this measure blood pressure?
A: No, the MAX30102 measures heart rate and blood oxygen saturation (SpO2) only. It cannot measure blood pressure.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, but since the MAX30102 operates at 1.8V-3.3V, you should use a logic level converter or an Arduino board with 3.3V logic to avoid damaging the sensor.
Q: How do I reduce noise in the readings?
A: Ensure steady contact, minimize movement, and shield the sensor from ambient light. Using digital filtering algorithms in your code also significantly improves signal quality.
