## Description

You've probably used sensors to check in on the environment, but have you ever read your pulse? Literally, sense each heartbeat with (amazing inbuilt disturbance rejection mind you) this heart rate and pulse oximeter sensor.

Using the I2C protocol tap into the MAX30102, a powerful biometric sensor. Similar sensors are used in the Fitbit, Apple watch, and Garmin watches.

If you want to make this sensor portable, use the two plated slots and add your own wristband.

**Note:** Please ensure to solder jumper on 3v3 side as outlined [here](https://github.com/coniferconifer/ESP32_MAX30102_simple-SpO2_plotter?tab=readme-ov-file#trouble-shooting). If you do not, I2C will not work.
