Reliable for student projects
We ordered ten of these for our university lab. All units performed consistently, and students found them easy to use for their final year health tech projects.

Easy to integrate
Plug and play with the standard Arduino libraries. The breakout board pins are clearly labeled, making wiring very straightforward for beginners.

Good sensor, needs calibration
The hardware quality is solid. It took some time to calibrate the readings against a medical device, but once tuned, it provides consistent data for development purposes.

Perfect for DIY Wearables
This module works flawlessly with my ESP32 project. The I2C communication is stable, and the library support is excellent. Great value for prototyping heart rate monitors.

Genuine chip confirmed
I was worried about fakes, but this is definitely a genuine Maxim Integrated chip. The signal-to-noise ratio is much better than the cheaper clones I tried before.

Great for learning
Bought this to understand how optical heart rate sensing works. It's sensitive to movement, which is expected, but perfect for stationary testing and learning algorithms.
Q: What is the maximum distance for detection?
A: This is a contact-based optical sensor. It requires direct skin contact or very close proximity (within a few millimeters) to function correctly; it is not designed for remote detection.
Q: Can this measure blood oxygen saturation (SpO2) accurately?
A: While the sensor hardware supports SpO2 calculation via red and IR light absorption, accurate medical-grade readings require complex calibration and algorithm tuning. It is suitable for educational and prototyping use.
Q: Is 5V logic safe for the I2C pins?
A: No, the MAX30102 operates at 1.8V to 3.3V. If you are using a 5V microcontroller like an Arduino Uno, you must use a logic level converter to prevent damaging the sensor.
Q: Does the package include a wrist strap?
A: No, this listing is for the sensor module only. You will need to design or purchase a separate enclosure and strap to create a wearable wrist device.
Q: Does this module come with example code for Arduino?
A: Yes, the product page includes links to popular open-source libraries like SparkFun MAX3010x Pulse and Proximity Sensor Library which contain ready-to-run examples.
