Solid component for the price

Does exactly what it says on the tin. The MAX30102 chip is a step up from older models. Just ensure you have a good 3.3V power supply for stable results.

Works but sensitive to motion

As expected for optical sensors, motion artifacts are an issue if not mounted securely. It's a great development tool, just remember this is a sensor module, not a finished medical device.

Good value but needs calibration

The hardware quality is solid for the price. You do need to spend some time calibrating the LED intensity to get consistent readings on different skin tones, but once set up, it works well.

5 FAQ

Q: What libraries work best with this sensor?

A: For Arduino, the 'SparkFun MAX3010x Pulse and Proximity Sensor Library' is widely used. For Python/Raspberry Pi, there are several open-source options available on GitHub.

Q: Can this measure blood pressure?

A: No, this sensor measures heart rate and blood oxygen saturation (SpO2) using photoplethysmography. It cannot measure blood pressure directly.

Q: Does it come with a protective case?

A: No, this item is sold as a bare breakout module intended for integration into custom projects or prototyping boards. You will need to design your own enclosure.

Q: How far should the sensor be from the skin?

A: The sensor requires direct contact or very close proximity (within a few millimeters) to the skin to accurately detect light reflection from blood flow.

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

A: Yes, but please note the sensor operates at 1.8V-3.3V. Most breakout boards include a voltage regulator, but you should verify your specific board's schematic before connecting to 5V logic lines.
