Heartbeat Rate Sensor MAX30100 Heart Sensor Module Sensor for Low Power Oxygen Pulse I2C Interface for Arduino - products that work with official Arduino boards

Description: HEART  is build with  MAX30100. MAX30100 is a complete pulse oximetry and heartrate sensor system solution designed for the demanding requirements of wearable devices. The MAX30100 provides very small total solution size without sacrificing optical or electrical performance. Minimal external hardware components are needed for integration into a wearable device. How do we use this to test the heart rate and?   Put your finger on the detection area. What is the communication protocol between M5 core and this unit?   I2C.
