MAX30102 Heart rate Sensor Module Puls detection Blood oxygen concentration test For Arduino STM32 Ultra-Low Power

The quality is ok does job it is ok overall but not super great quality heat sensor. Check some from neeer model from max that is more accurate

Prompt shipping and exactly as advertised!

I got these fairly quickly and I was finally able to test them. there is not a lot of information available for them. also the seller does not provide any links to find the information. the worst part is that one of the sensors is missing a piece of it. there is supposed to be a black cover for the leds and sensor. it is missing on one.

Before use..........

I tested this module for heart‑beat counting, SpO₂, temperature, and basic presence detection. Accuracy aside, essentially all of these functions do work. One caution: for precise readings, your finger needs full contact with the sensor surface. If you solder header pins straight in, they can interfere with proper access to the sensor, so plan ahead before committing to the build.

Excellent
