## Features

- Integrates a red LED, a infrared LED, aphotodetector, an optical equipment and a low noise electronic circuit with environmental light suppression.
- The standard I2C compatible communication interface can transmit the collected data to Arduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation.
- Apply to wearable device for heart rate and blood oxygen collection, worn on fingers, ear lobes, wrists and other places.
- The chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always be maintained.

## Questions & Answers

**Q: how many milliamps does the device use?**
A: If it helps, the Sparkfun library for this family of parts includes a LED drive setting from 0 to 50 mA.  So it looks like the part could draw up to 50 mA just for the LED (but that is multiplied by whatever duty cycle it uses; it's never 100%).  In my case I found I only needed about 20% of the full drive to get a good signal and the device draws about 8 mA average while running, in one (of MANY) operating modes.

**Q: How small an arduino is this compatable with? An attiny85?**
A: It uses I2C interface so as long as you have that on the microcontroller it should be fine. 
Attiny85 should work. I allows simulating I2C on 2 of its pins and has an arduino IDE library available.

**Q: Where can I see the schematic (circuit connection) or pin descriptions?**
A: You can search online for  "MH-ET-Live" which will show you a schematic for the module. Also, there are Arduino projects indicating how to use the device; search on  "Arduino MAX30102". Also, search for "MAX30102 datasheet" for more detailed pin descriptions.

The sensor itself works OK, in that the raw heartrate signal looks reasonably useful at first glance. However I would say the calculated BPM and SPO2 values from the Sparkfun MAX3010x library for Arduino are rather underwhelming, so far as consistency and accuracy. I think this might look better with some more software effort, but that remains to be seen. If there's any motion or change in pressure of the sensor against the skin, that swamps the signal. I provided +5V in to the board; it has its own 3.3V and 1.8V regulators for the chip. You need to either provide your own I2C pullup resistors offboard, or solder-bridge 2 out of the 3 the tiny pads on the back to select a 3.3V or 1.8V level pullup for the I2C signals SDA, SCL.
